Compatible with sealed system heat sources.
The ThermaQ ST SSB (Sealed System Boiler) model creates a hot water only store with an independent space heating circuit fuelled by a controllable gas or oil boiler.
The sealed system boiler is used as the primary energy input and because it is sealed and pressurised it allows the radiators to be positioned above where the unit is situated, meaning the cylinder can be sited anywhere in the property. This also means the radiators are fed directly from the boiler and not via the store like some systems in the range. This leads to flexibility in feed and expansion installation.
These units will also operate using a smaller Feed & Expansion tank as the central heating circuit is sealed and separate to the store. The system is also popular as they can be installed using either S or Y plan configurations.
