Gas boiler installations, Bristol

Professional gas boiler installers.

At AMW Heating, our team of Gas Safe registered engineers supplies and installs a wide range of brand new gas boilers for homes in Bristol and the surrounding areas. Whether you need a combi boiler for instant hot water, a system boiler for a home with higher demand or a regular boiler for a traditional setup, we’ll fit it properly.

Gas boilers are the most popular way to heat a home connected to the mains gas network. They warm rooms quickly, hold a steady temperature and give you good control over your heating. With an annual service, a modern gas boiler gives long-term reliability and value for money.

We work with leading manufacturers such as Worcester Bosch, so you get a quality boiler that’s efficient, durable and built to last. We can recommend a boiler model to suit your home, or you can start with our online boiler quote.

Choosing a gas boiler

Which gas boiler is right for your home?

The right gas boiler depends on the size of your home, how many bathrooms you have and how much hot water you use at once. Here’s how the options compare.

Gas combi boilers

Heat water instantly from the mains as you need it, with no hot water cylinder or tank. Compact and efficient, and the usual choice for flats and smaller homes with one bathroom. Combi boilers.

Gas system boilers

Work with a hot water cylinder that stores heated water ready to use, so several taps and showers can run at once. A practical choice for larger households. Hot water cylinders.

Gas regular boilers

Also called conventional or heat-only boilers, they work with a cylinder and a cold water tank in the loft. Often the simplest swap in older homes with a traditional system.

Sizing it properly

A boiler that’s too small struggles on cold days; one that’s too big wastes gas. We size your new boiler to your home’s heating and hot water demand at the survey.

Controls that suit you

A new boiler is the ideal time to upgrade your controls. We fit smart thermostats including Nest, Hive and Worcester Bosch’s Comfort 2. Are smart thermostats worth it?

Moving or changing your system

A new boiler is a good chance to move it somewhere more convenient or switch from a regular to a combi setup. We’ll talk through the options and include everything in your quote.

Gas boiler replacement

Is your old gas boiler costing you?

Most gas boilers last around 10 to 20 years with proper maintenance. When faults keep coming back and the cost of repairs starts to outweigh the cost of a replacement, a new, efficient gas boiler is usually the better investment.

We’ll always tell you honestly if a repair still makes sense: read should I repair or replace my boiler? or see the signs it’s time to replace your old boiler.

[VERIFY WITH AMW — the smart controls list (Nest, Hive, Comfort 2, from the live smart-controls band; Hive’s “up to £151 a year” saving dropped)]

Signs it may be time to replace:

Smell gas? Don’t use electrical switches or naked flames. Open windows, turn off the gas at the meter if you can, leave the property and call the National Gas Emergency Service on 0800 111 999.

The main difference is how they deliver hot water. A combi boiler heats water instantly, only as you need it, which is why you hear it fire up when you turn on a hot tap. A system boiler heats a store of water in a cylinder and keeps it hot for use through the day. If you have a larger home with room for a cylinder and several people using hot water, a system boiler is often more practical. If space is limited and your household is smaller, a combi usually suits better.

Choosing a boiler can be confusing. Our engineers will assess your home, talk through your options and your budget, and help you make an informed choice. You can also get a recommendation by answering a few simple questions with our new boiler quote, or see our recommended boiler makes and models.

A straightforward gas boiler replacement typically takes a single day. Moving the boiler or changing the type of system takes longer, and we’ll let you know how long your installation will take before the day.

Gas boilers typically last around 10 to 20 years when properly maintained. We suggest replacing yours when persistent faults emerge and repairs start to cost more than a replacement.

We strongly advise a gas boiler service at least once a year to keep it running safely and efficiently. Our Gas Safe registered engineers carry out a thorough inspection, finding small faults before they turn into long-term problems. An annual service also keeps your boiler guarantee or warranty valid.
