Boiler vs Water Heater: You might’ve heard the words ‘boiler’ and ‘water heater’ and wondered what the difference is. After all, if you’re looking to buy a new system for your home, it’s important to know which one is right for you. This handy guide will explain the differences between a boiler and a water heater, as well as what the two terms mean and which one might suit your home best.

What Is a Boiler?

A boiler provides heat for both your central heating and your hot water. This makes it an essential part of any household setup.

Types of Boiler

• Combi boiler – Gives you heat and hot water straight from one unit, without the need for a separate cylinder.

• System boiler – Provides hot water via a cylinder, ideal for homes with higher demand.

• Conventional (regular) boiler – Perfect for properties with traditional systems and multiple bathrooms.

At JWD Heating, we install, maintain, and service all types of boilers in Brentwood and the surrounding areas. Our team will help you choose the right option for your home.

What Is a Water Heater?

A water heater supplies hot water to your taps, showers, and appliances. Unlike a boiler, it doesn’t provide any central heating.

Water heaters are typically found in commercial properties or homes using alternative heating systems.

Types of Water Heaters

• Tank water heater – Heats and stores water in advance for later use.

• Tankless water heater – Heats water on demand, saving space and improving energy efficiency.

Boiler vs Water Heater: The Key Differences

The main difference lies in function. A boiler supplies both heat and hot water. A water heater only supplies hot water for your taps and appliances.

Boilers are the most popular choice in UK homes, especially those with radiators or underfloor heating. Water heaters are better suited to smaller properties, extensions, or homes with electric heating systems.

Which Is Right for My Home?

It all depends on your property’s heating and hot water needs.

• Need both heat and hot water from one system? A boiler is likely the best fit.

• Only need hot water for one room, an annexe, or an outbuilding? A water heater could be ideal.

Selecting between a boiler and a heat pump for efficient and affordable home heating presents a challenging choice. Many customers at Boiler vs heat pump – which is right for your home? Discover the pros, cons, and expert advice from JWD Heating & Plumbing in Brentwood, Essex. Request information about the advantages and disadvantages of both heating systems because of the increasing interest in renewable energy options. This blog analyses the essential distinctions that will guide you in selecting the heating system which best matches your home requirements and lifestyle choices.

What Is a Boiler?

Boilers function as heating systems that use gas combustion (or oil in some cases) to produce hot water, which gets distributed through radiators or underfloor heating systems. Combi boilers represent the pinnacle of modern gas boiler efficiency by delivering simultaneous heating and on-demand hot water delivery.

Pros of Boilers:

• Excellent for colder climates like the UK
• Reliable and fast heat output
• Lower upfront cost than heat pumps
• Compatible with existing pipework and radiators
• Cons of Boilers:
  Higher carbon emissions than heat pumps
• Annual servicing is necessary to maintain safety and efficiency standards.
• Dependent on fossil fuels

What Is a Heat Pump?

A heat pump works by extracting heat from outdoor air or the earth below and delivering that heat into your residential space. The heat pump operates using electricity and serves as a sustainable heating option when compared to gas heating systems.

Pros of Heat Pumps:

• Environmentally friendly
• Lower running costs over time
• Eligible for government grants and incentives
• Underfloor heating systems and well-insulated buildings experience optimal performance from heat pumps.

Cons of Heat Pumps:

• Higher installation cost
• May require upgrading insulation or radiators
• The heat pump system loses its efficiency when operating in extremely cold weather without additional heating support.

Which system is better for your home: a boiler or a heat pump?

Choosing the right system relies on evaluating your home’s layout as well as the quality of its insulation and your available budget.

Opt for a boiler when you require an uncomplicated system replacement, already possess gas infrastructure, and demand robust heating capabilities throughout winter.

Heat pumps are a good choice for those who prioritise long-term financial savings and environmental benefits and can afford the upfront expenses.

A Comprehensive Guide To Turn Off Your Boiler Step By Step
Every homeowner needs to understand the proper method to safely turn their boiler off. Turning off your system correctly when traveling or performing maintenance helps maintain home safety and energy efficiency. The JWD Heating team provides helpful guidance as this guide takes you step by step through the boiler shutdown process.

Multiple situations require you to turn your boiler off to maintain safety and efficiency in your home.

Multiple scenarios exist where you should switch your system off.

During long periods away from home

For planned maintenance or cleaning

If your boiler experiences a leak or develops a fault

Reset your system by following the instructions after receiving a fault code.

When switching energy providers or systems

No matter what the situation demands turning off your system you need to know the right procedure to prevent damage and safety hazards.

Step 1: Identify Your Boiler Type

You must first determine your boiler type before learning how to turn it off. The majority of UK homes contain one of these three types of boilers:

A combi boiler functions as a space-saving unit that heats both water and radiators directly.

The system relies on an independent hot water cylinder for operation.

A conventional boiler operates by utilizing both a hot water tank and cold water storage.

Although most shutdown procedures share similarities, they may show small differences according to your boiler model.

Step 2: Locate the Boiler Switch

The power switch for modern boilers is generally located either on the system or in close proximity. The power switch may display either the words ‘on/off’ or a power symbol. Make sure you identify the exact switch needed before you move forward.

Switch off power to your boiler using the separate fused spur switch which features a small red light.

Step 3: Switch Off the Boiler

After discovering the switch you just turn it off. The power down of the system might produce audible signs or cause the display to become blank. Once the boiler uses neither gas nor electricity it becomes safe to perform maintenance work or leave it switched off until future use.

Step 4: Turn Off the Gas Supply (If Needed)

In the case of a suspected gas leak or emergency, turning off the system alone will not resolve the situation. Turn off your gas emergency control valve which is normally located near the gas meter. Dial 0800 111 999 to reach the National Gas Emergency Service whenever you suspect there is a gas leak.

Step 5: Inform Your Heating Engineer

Whenever you switch off your system because of a problem or worry, you should seek professional inspection. Our team at JWD Heating delivers approachable community support to ensure your heater functions properly and safely.

A Few Extra Tips

Consult your user manual to find specific operating instructions for your model.

Do not try to inspect or fix internal boiler components unless you hold a Gas Safe registration.

Adjust your settings with the timer or thermostat if a complete shutdown is unnecessary.

How to remove airlock from water pipes: An airlock in your water pipes can cause frustrating disruptions, leading to weak or no water flow from your taps. Fortunately, removing an airlock is often a straightforward task that you can do yourself. In this guide, we’ll explain what an airlock is, how to identify it, and the steps you can take to fix the issue quickly.

What Is an Airlock in Water Pipes?

An airlock occurs when trapped air prevents water from flowing freely through your plumbing system. This is more common in hot water pipes and can lead to inconsistent or reduced water pressure. Left unresolved, an airlock can affect your entire water supply and cause ongoing issues with your plumbing.

Signs of an Airlock in Your Pipes

If you suspect an airlock, look out for these common signs:

• No water or weak flow from taps – Particularly from the hot water side.
• Sputtering taps – Water coming out in bursts instead of a steady stream.
• Gurgling noises – Air trapped in the pipes can create bubbling or gurgling sounds.

How to Remove an Airlock from Water Pipes

Here are a few simple methods to clear an airlock from your plumbing system:

Method 1: The Hosepipe Trick

This method uses water pressure to push the trapped air out of your system.

1. Turn Off Your Taps – Ensure all taps in your home are off.
2. Attach a Hosepipe – Connect a hose between a working cold water tap and the affected hot water tap.
3. Turn On Both Taps – Open the cold tap first, then the hot tap. The cold water pressure should force the air out.
4. Keep Running for a Few Minutes – Allow the water to flow for about 2-3 minutes.
5. Turn Off the Taps – Close the hot tap first, then the cold tap. Remove the hose and test the hot tap.

Method 2: Running the Taps Alternately

1. Turn On the Affected Tap – Let it run at a trickle.
2. Turn On Another Tap – Open a tap at a lower level in your home to help push air out.
3. Alternate Opening and Closing Taps – Doing this for a few minutes may help dislodge trapped air.

Method 3: Using a Plunger

For stubborn airlocks, a plunger may help:

1. Partially Fill the Sink – This ensures a good seal.
2. Place the Plunger Over the Tap Outlet – Ensure it covers the opening completely.
3. Pump the Plunger – Repeatedly plunge to create pressure and dislodge the airlock.
4. Test the Tap – If the water flows normally, the airlock is gone.

Preventing Future Airlocks

To reduce the risk of airlocks in your plumbing:

• Regularly run taps – Especially hot water taps.
• Maintain consistent water pressure – Check for leaks or system faults.
• Ensure professional installation – Poor plumbing work can contribute to recurring airlocks.

When to Call a Professional

If you’ve tried these methods and your taps are still not functioning correctly, it may indicate a deeper plumbing issue. JWD Heating & Plumbing has over 20 years of experience in diagnosing and resolving plumbing problems. Contact us today for expert assistance.

Keeping your central heating system in top condition ensures your home stays warm and energy-efficient. One common maintenance task is bleeding your boiler, but when should you do it? In this guide, we’ll explore the signs that indicate it’s time to bleed your boiler and how doing so can improve your heating system’s performance.

What Does It Mean to Bleed a Boiler?

Bleeding a boiler involves releasing trapped air from the heating system. Over time, air can accumulate in your radiators and pipes, creating air pockets that prevent hot water from circulating efficiently. This can lead to cold spots on radiators and reduced heating performance.

Signs Your Boiler Needs Bleeding

If you notice any of the following signs, it may be time to bleed your boiler:

• Cold Spots on Radiators – If your radiators are warm at the bottom but cold at the top, trapped air is likely preventing proper heat distribution.
• Gurgling or Banging Noises – Unusual noises from your heating system often indicate air bubbles within the pipes.
• Reduced Heating Efficiency – If your home takes longer to warm up or your heating bills are increasing, your system may not be working efficiently.
• Boiler Pressure Issues – A drop in boiler pressure can be a sign of air trapped in the system.

How to Bleed a Boiler Safely

Before attempting to bleed your boiler, ensure your heating system is switched off and cooled down. Follow these simple steps:

1. Locate the Bleed Valve – This is usually found at the top of each radiator.
2. Use a Radiator Key – Turn the valve slowly anti-clockwise until you hear a hissing sound, which indicates air escaping.
3. Catch Any Water – Once water starts to flow steadily, close the valve.
4. Check Boiler Pressure – After bleeding all necessary radiators, check the boiler pressure and top it up if needed.
5. Turn the Heating Back On – Ensure your radiators heat evenly and your system runs smoothly.

How Often Should You Bleed Your Boiler?

It’s recommended to check your radiators for cold spots at least once a year, particularly before winter. If you frequently experience air buildup, it may indicate a deeper issue within your heating system, requiring professional attention.

When to Call a Professional

While bleeding a boiler is a straightforward task, persistent heating problems may require expert assistance. JWD Heating & Plumbing has over 20 years of experience in boiler repairs and servicing. If your boiler continues to lose pressure, makes excessive noise, or fails to heat properly, our trained engineers are here to help.

A boiler with stable pressure is essential for keeping your heating system working efficiently. If you’ve noticed a pressure drop, it could indicate an underlying issue that needs attention. Low boiler pressure can lead to poor heating performance and even system failures if left unresolved. Here’s a look at some common causes and what you can do to fix them.

1. Leaks in the System

One of the most common reasons for a drop in boiler pressure is a leak somewhere in the system. This could be in the pipework, radiators, or even within the boiler itself. Small leaks may go unnoticed, but over time, they can cause a significant loss of pressure. If you suspect a leak, check for damp patches, rusted pipes, or water stains around your radiators and boiler.

2. Bleeding Radiators

If you have recently bled your radiators, you may have inadvertently caused a pressure drop in your boiler. When air is released from the system, it can lower the overall water pressure. This can usually be resolved by topping up the pressure using your boiler’s filling loop.

3. Faulty Pressure Relief Valve

The pressure relief valve is designed to release excess pressure if it gets too high. However, if the valve is faulty or has been triggered too often, it may allow water to escape, leading to a continuous drop in pressure. A professional heating engineer can check whether the valve needs repair or replacement.

4. Expansion Vessel Issues

Modern boilers are fitted with an expansion vessel that helps maintain consistent pressure. If this component is faulty or loses its charge, the system may struggle to hold pressure properly. This usually requires expert inspection and maintenance.

5. System Filling Issues

Your boiler relies on the right level of water to function correctly. If there’s been an issue with filling the system—such as a partially closed valve or incorrect pressure setting—the pressure may drop. Topping up the water using the filling loop can often resolve the issue.

How to Repressurise Your Boiler

If your boiler pressure is too low, you may be able to fix it yourself by following these steps:

1. Locate the filling loop, usually a silver, flexible hose beneath the boiler.
2. Open the valves slowly to allow water to enter the system.
3. Watch the pressure gauge and close the valves when it reaches the recommended level (typically between 1 and 1.5 bar).
4. Restart your boiler and check if the pressure holds.

When to Call a Professional

If you continue to experience pressure drops despite topping up your system, it’s best to call a professional. Persistent issues could indicate a more serious problem, such as internal component failure or a hidden leak. At JWD Heating & Plumbing, our expert team can diagnose and repair any boiler pressure issues quickly and efficiently.
