A heat only (sometimes referred to as regular, conventional, open vent) boiler provides the heat for a home's central heating system and hot water cylinder.
A heat only boiler is suited to servicing larger properties with multiple bathrooms/radiators or a business premises with a high water demand.
Heat only boilers do require sufficient installation space within a property, as they use two storage tanks (feed & expansion) as well as the aforementioned hot water cylinder.
Although a combi is generally considered more space saving, a heat only boiler is still compact and can supply more bathrooms with hot running water than a combi can.

Heat-only boilers require more space due to their need for both a hot water cylinder and a cold water storage tank, which can be a drawback for homes with limited space. They may also be less efficient than modern alternatives like combi or system boilers, as they can lose heat while storing hot water.
A heat-only boiler should typically be set between 60-70°C for optimal efficiency, ensuring the water is hot enough to supply your radiators and taps without causing overheating or unnecessary energy consumption.
Heat-only boilers are ideal for larger homes or properties with multiple bathrooms, providing a steady supply of hot water to multiple outlets simultaneously. They are also more reliable for homes with low water pressure, as they rely on a water storage tank rather than pressure from the mains.
The number of radiators a heat-only boiler can run depends on its output capacity. Most standard heat-only boilers can manage 10-15 radiators, but larger models can support even more, making them ideal for bigger homes.
With proper maintenance, a heat-only boiler can last 10-15 years. Regular servicing and timely repairs can extend its lifespan, ensuring continued efficiency and reliability over time.
Yes, you can replace a heat-only boiler with a system boiler, but this would require adjustments to the existing pipework and possibly the removal of the cold water storage tank. Consulting a professional is advisable to assess your home’s specific needs.
A system boiler might be better suited for homes where space is a concern, as it eliminates the need for a cold water tank. It also offers better energy efficiency and quicker hot water delivery. However, heat-only boilers can be more beneficial for homes with high hot water demand. The best choice depends on your specific home requirements.
