Connecting the FHT Stove
to Heating Systems
The FHT Stove is unique!   Designed for safe, simple, direct connection into any central heating system. Heat transfer can be turned ‘on’ or ‘off’ whenever required, giving unparalleled control over comfort - Switchable heat transfer!
FHT Stove impression
Around half the stove heat output can be diverted to the central heating circuit at the flick of a switch, so reducing the heat output to the room and sending excess heat to other rooms.

The ultimate comfort control!

It can work on independent circuits or in parallel with your heating system, including combi boilers, low temperature heat pump circuits and under-floor heating systems.

No special circuits are required. No ‘link up’ or gravity fed systems need be installed. Connects directly to existing or new systems at low cost.

Some of the possible connection configurations are illustrated below.

EcoDesign Regulations - the FHT Stove is one of the very few stove designs which can connect to central heating systems following the introduction of EcoDesign regulations in January 2022 which significanlty reduce the emissions from stoves. Traditional ‘back boiler’ stoves cannot meet these regulations.

Direct connection to an existing central heating system Up
Central Heating Connection

  • Connected like a radiator to the nearest central heating flow and return pipes

  • Connects to pressurised or open-vented heating systems

  • Pump allows the FHT Stove to operate either independently of the CH boiler or in parallel with the CH boiler

  • Non-return valve prevents back flow from the CH system pump when the fan is off

  • FHT Stove can be integrated with existing central heating control for optimum benefit

  • Discrete water connections can be made in small bore tubing (10 or 15mm)

Independent heating circuits Up
Independent Heating Connection

  • Where the FHT Stove is the only source of heat

  • Pump and expansion vessel or header tank required

  • Radiators can be controlled with TRVs or on/off valves if required

  • FHT Stove can cycle on and off thermostatically like a central heating boiler

  • Radiators at the same level, lower than and/or higher than the stove

  • Connection via conventional pipe bores

  • Good option to heat the ‘home office’

Connection to thermal stores and other renewable heating technologies Up
Renewable Heating Connection

  • Simple link to thermal stores via a pressurised or open-vented loop

  • Other Renewable heat sources can be connected in the same system

  • High temperature ‘top up’ for low temperature systems

  • Good match to Air-Source Heat Pump (ASHP) systems

  • Ideal for low energy New Build and Refurbishment projects

Distributing stove heat across open-plan spaces Up
Renewable Heating Connection

  • For the ‘grand design’ with large open-plan living spaces

  • Either an independent circuit or as part of the central heating system

  • Good match to underfloor heating systems

Simple connection to hot water (immersion) tanks Up
Immersion tank heating
  • No header tank required (can be pressurised)

  • Hot water tank can be located anywhere - not restricted to being above the stove

  • Water temperature can be thermostatically controlled - fail-safe operation

  • Demand Side Management option for Electricity Suppliers - displaces electric immersion heating on the coldest days of the year

  • Good match for reducing stove heat output at the end of the evening to heat water for the morning

Off-grid homes, boats, DC systems Up
Off Grid Homes and Boats
  • Off-grid systems relying on DC electrical supplies (batteries)

  • Fail-safe operation of the FHT Stove ensures safe operation with battery systems

  • Distribute heat at the same level as the stove - boats and eco-cabins
