Which is the best boiler for a larger house?

The real driver for selecting the right boiler for a larger home is your hot water requirements. If you need lots of hot water, a hot water cylinder will be preferable. Whilst large combis are available that provide lots of hot water, they can be very inefficient on the heating system side.

Can a combi boiler be used for two bathrooms?

Whilst large combis are available that provide lots of hot water, they can be very inefficient on the heating system side. Some combi boiler manufacturers have found the right balance of providing lots of hot water without compromising efficiency, but the maximum they can do is still only two bathrooms.

Do you need a boiler for a 3 bedroom semi?

For a three-bedroom semi with one main bathroom, we’d typically advise that you install a storage combi boiler. These systems will heat water on demand, however they also have an integrated tank for storing some hot water too. This means you don’t need a separate bulky storage tank that could take up precious space.

How many LPM does a combi boiler give?

These larger outputs on combi boilers relate to hot water performance. For example, a 24kW combi will give around 9 litres per minute (LPM) of hot water. A 38-42kW boiler will give 14-6 LPM. The true outputs for heating on combi boilers are 16kW and upwards, which will heat the majority of larger UK homes.

How big of a boiler do I need for my home?

The nature of steam boilers, and steam itself, means that the boiler must be sized for the volume of radiation in the home. Too little steam or too much steam can cause problems, ranging from a noisy heating system to an uncomfortable home.

How is hot water released from a boiler?

As the flame and exhaust gases pass over the tubes of the heat exchanger, the water inside absorbs heat. The hot water is pumped to the baseboard heaters/radiators to release its stored heat before returning to the heat exchanger to repeat the process. This is called the boiler water loop, since it is a circular system.

What are the parts of a hot water boiler?

A hot water boiler consists of a fuel burner(s), an ignition source, a blower fan, a refractory liner (to protect the floor of the boiler and building), a heat exchanger, a circulating pump, an expansion tank and at least one radiator.

What kind of fuel does a hot water boiler use?

They can be fired using fuel oil or natural gas. A hot water boiler consists of a fuel burner(s), an ignition source, a blower fan, a refractory liner (to protect the floor of the boiler and building), a heat exchanger, a circulating pump, an expansion tank and at least one radiator.
