Question for HE127A eCOHeat (Added 4/11/15 )
Having a 3.25kw solar system installed this week. No immersion heater currently fitted to the cylinder, propose to use one of your low power 1kw units.
Cylinder states 57mm connection I am used to BSP is this 1.5 BSP ?
Soft water area vented system.
could you make a recommendation ?
