Surecal Copper boilers are made of the finest quality materials guaranteeing the ultimate performance and reliability. The boiler is made of 100% copper which expands and contracts without impairing the welds and prolongs the life of the unit. The copper heat exchanger is threaded with comb fins and provides unrivalled heat recovery, quickly heating the water and providing water at elevated temperatures when compared to stainless steel calorifiers. Immersion heaters are made of titanium as standard and the boiler is insulated in a polyurethane jacket which will retain the heat for up to 24 hours after the engine has been switched off. The higher temperature achieved using copper coil heat recovery requires the addition of a thermostatic mixer valve, fitted as standard on the hot water supply, for the safety of users and effectively providing hot water in a greater volume than the tank capacity. 

Surecal Copper Calorifiers come with:
Thermostatic mixer valve
4 bar pressure release valve
1kw immersion heater
Non return valve
Stainless steel saddles and brackets

Calorifiers are supplied with spigots suitable for push fit connection on the cold water inlet, hot water outlet and pressure release valve. If you do not have push fit connectors attached to your hose please add part CU55160
