You can have a water softener in combination with our boiler as it will prevent the hot water circuit from scaling up and losing efficiency. However, the central heating circuit should be filled with hard water and a chemical inhibitor. This can be done by using the water softener bypass when filling or topping up. Alternatively, the filling loop feed can be connected upstream of the water softener.
Underfloor heating may be installed with our entire range of boilers and heat pumps, with the exception of air to air heat pumps. In particular, underfloor heating is ideal for use with heat pumps which provides the added benefit of extra efficiency. If you are considering installing underfloor heating, please be aware that additional external controls and pumps may be required. *Please be aware of zoning and the suitability of each appliance to these requirements.
