Our specially designed stainless steel high recovery tank in tank calorifiers are capable of outputs from 24 l/hr to 2438 l/hr of domestic hot water at 60degC when supplied with LTHW. Available in 9 sizes ranging from 107ltrs to 1000ltrs, suitable for all secondary systems with working pressures up to a maximum of 10 bar.

McCallum water Heating have a wide range of domestic cylinders that will cater for every application from 90 to 500litres. Our Stainless Steel range uses the very latest high specification Duplex to resist all forms of corrosion whilst it's high mechanical strength gives it the strength for long life and allows factory testing of 12bar, four times it's 3 bar max working pressure.

The maximiser has been developed to meet today's need for a compact calorifier which will respond to high peak loads with minimal demand for boiler power. This high output semi-storage calorifier is the ultimate solution to space limitations, power regulation, fluctuations in demand and energy savings.

When space is tight and hot water needs to be carefully controlled, that's when the new HT-Breeze range of plate heat exchangers comes into its own. Thirteen outputs, 0.25 to 5.00 litres/second, all on the same compact 340mm x 750mm footprint. New standard features mean the new HT-Breeze gives even better control of hot water generation.
