Thermal Stores & Twin-Coil Cylinders
Thermal store and twin-coil cylinder installation in North London — for solar, heat pump and multi-source heating systems.
Thermal Stores & Twin-Coil Cylinders in North London, done properly the first time
A twin-coil cylinder lets two heat sources feed the same hot water — typically a boiler plus solar thermal or a heat pump. A thermal store inverts the arrangement, storing heated primary water and passing it through a plate exchanger for instant mains-pressure hot water.
Both are specialist installs, and both need careful control strategy to be worth the money. We design the controls as part of the job, not as an afterthought.
This is increasingly relevant in Barnet homes adding solar or planning a phased move to a heat pump.
