Strom Electric Boiler (System) 21KW Three Phase 400V

The Strom Electrical Combination Boiler has been designed from the ground up to be familiar to anyone with any experience of Gas, Oil, or LPG boilers. When running the Electric System Boiler in conjunction with a Hot Water Cylinder on Economy 10 tariffs the boiler stands up as a perfectly feasible option against Oil & LPG in terms of running cost. The boiler is ideal for replacing existing tank-based fuels, where gas is not available, and where the benefits of the Electric Boiler outweigh the monthly running costs. The Strom Electric Combination Boiler really is the pinnacle of electric heating and features a whole host of innovative features and benefits.
