What heating system works best with a Worcester Bosch heat pump?

Worcester Bosch recommend using underfloor heating with a heat pump to maximise the efficiency of the system. Heat pumps operate most efficiently at lower flow temperatures, and underfloor heating is designed to work effectively at these temperatures due to its large surface area. Radiators can also be used but may need to be larger than those used with a conventional boiler.

Can I use artificially softened water in my Worcester Bosch heating system?

Worcester Bosch recommend that water softeners can be used to prevent scaling in the hot water circuit, but the central heating circuit should be filled with hard water and a chemical inhibitor instead. When filling or topping up the heating system, either use the water softener bypass or connect the filling loop feed upstream of the water softener.

Do I need a cylinder with a Worcester Bosch heat pump?

Yes, Worcester Bosch heat pumps require a hot water cylinder as they do not provide instant hot water like a combi boiler. The Greenstore range of cylinders is designed specifically to work efficiently with Worcester Bosch heat pumps.

What is the difference between a timer, programmer and programmable room thermostat?

A boiler timer is a basic device that allows you to set times for your central heating, operating at the same times daily. A programmer allows you to set different times for heating and hot water, and can vary schedules across different days of the week. A programmable room thermostat combines timing with temperature control, allowing you to set different temperatures for different times. Worcester Bosch recommend settings of 21°C for comfort periods and 15°C for economy periods.
