Combining domestic hot water systems with Central Heating
A Unique and Efficient Heating Combination
Unlike many other methods of heating your home, our central heating systems are able to meet not only its space heating requirements, but also its entire hot water supply for baths, showers and the like.
There are two ways in which a warm water central heating system can service a domestic hot water supply:
- Combi boilers are designed to produce sufficient quantities of hot water to service the central heating system and produce instantaneous hot water for domestic use. In the case of storage combi boilers, the domestic hot water cylinder is incorporated into the boiler unit itself (suitable for homes with up to two bathrooms).
- In system boilers, the water pumped around the central heating system can be used to heat the domestic hot water indirectly. It is diverted from the radiators or underfloor pipes and into an internal coil within a cylinder. The coil is heated by the water passing through it, and this heat is in turn transferred to the water stored in the cylinder. These cylinders are known as indirectly heated mains pressure cylinders. The domestic hot water is never in direct contact with the water used for central heating.
