Halstock stainless steel calorifier
Stainless steel single coil and twin coil calorifiers for indirect hot water.
5 unvented calorifier models and 4 open-vented calorifiers available with continuous outputs (@44°C ∆T) of 390, 527, 1,843 and 2,106 l/h.
- Power outputs 20-108kW and storage capacities 305-965 litres
- Indirect method of producing safe and hygienic domestic hot water (want to understand the difference between Indirect vs Direct Hot Water Systems?)
- Fast recovery for constant hot water – as little as 13 minutes (Recovery times for 70% of the cylinder volume to 50°C 13-22 minutes)
- Hot water cylinder and coil made out of corrosion resistant stainless steel for a long life backed up by a 5 year cylinder warranty
- Now available with twin coils for flexibility and high performance hot water (models 500-965 only)
- Can be integrated with solar thermal for a renewable energy option
- Minimal heat loss for maximum economy thanks to layer of CFC-free polyurethane tank insulation under protective plastisol cladding
- Highly efficient heat transfer from a corrugated coil design
- Low maintenance as no sacrificial anodes or powered corrosion protection systems needed
- Can be located wherever convenient
- Versatility in use – coupled to Hamworthy commercial boilers or backup via immersion heater
- UK manufactured hot water calorifiers
- Compliant with Energy Labelling requirements of ErP
- Available for next day delivery (dependent on stock availability, charges apply, order cut-off 12pm).

- To provide domestic hot water for any type of commercial building.
- Designed for use with natural gas, LPG or oil-fired commercial boilers for primary heat source.
- Direct heating via optional Incoloy 800 electrical immersion heaters.
- Suited to all areas of the UK, particularly locations with soft water (read here why).
- Electric immersion heater kits
- Top-to-bottom re-circulation/de-stratification kit to prevent stratification and protect against legionella within the water heater (factory fitted – please specify at time of ordering)
- Choose from a wide range of service contracts to help maintain optimum performance.
Riverside Childrens Centre, Canterbury
Sector: Education and childcare
Project: The nursery provides childcare and cooked midday meals for children. A hot water priority strategy using built-in boiler controls made the combination of a hot water circuit with a low temperature underfloor heating circuit possible.
Building: Nursery refurbishment
Application: Space heating, 43kW, indirect fired DHWLearn more
