Baxi Heat Only (Solo) Boilers Price Range – Efficient Models

Heat only boilers, also called conventional or regular boilers are the oldest type of domestic boiler and still relatively common in the UK.

Regular/heat only boilers work together with a hot water storage tank/cylinder and a feeder tank (typically placed in the attic).

The cold water storage tank (in the attic) draws water from the cold water mains when it needs to be refilled.

Baxi heat only boiler models are suitable for both open vented and closed vented systems.

Regular/heat only boilers remain a good choice for larger properties that have considerable hot water demands.

Why would you choose a regular vs a system boiler?

Often properties that already have a heat only boiler installed have pipework already in place that would struggle to handle the high pressure of a more modern system boiler.

Baxi Boilers Prices & Costs UK Conclusion

Baxi boilers is a well established UK boiler brand boiler with a wide selection of boilers, including combi, regular and system boilers, as well as heat pumps.

They are also available in a wide variety of different sizes/power outputs, so you will easily be able to acquire one that will meet your home’s hot water demands.

However, having said that, we would probably recommend a different boiler brand purely based on other brands offering more generous warranty periods.

For instance, the boiler manufacturer Worcester Bosch offers a very generous decade long guarantee (not just a warranty).
