What's involved

We'll work out whether the unit is worth repairing or whether replacement makes more sense, and we'll be straight with you either way. If it's a replacement, we'll talk through the system types that suit the property, the gas or electrical supply available, and what the changeover involves.

Questions we get asked

Do you repair as well as replace?

Yes. Where a repair is the sensible option we'll tell you, rather than pushing a new unit.

Which system types do you install?

Gas continuous flow, gas storage, electric storage and heat pump hot water systems.

Can I send photos of my unit?

Please do. Photos of the unit and its data plate help us give you a more accurate answer up front.

Do you do commercial hot water work?

Yes, we work with businesses and property managers as well as homeowners.

Let's get it sorted.
