Hot Water Units

Hot water system supply, installation and repair, all major brands.

Service details

No hot water is one of those faults you want sorted the same day, not next week. Kel-Tech supplies, installs and repairs every type of residential hot water system across the Swan Valley, and we carry common parts and units so we can usually get you back up and running fast. Whether your old unit has finally given out or you are upgrading to something more efficient, we will talk you through the options and the cost before we start, so there are no surprises.

What’s included

Signs your hot water system is on the way out

Hot water systems rarely fail without warning. Water that runs warm instead of hot, takes longer to heat, or runs out faster than it used to often means the unit is struggling. Rusty or discoloured water, water pooling around the base of the tank, banging or knocking noises, or a pilot light that keeps going out are all worth a call. If your system is more than ten years old and starting to play up, it is usually worth weighing a repair against a replacement rather than paying to patch a unit near the end of its life.

Every type of system

We work across all four main types. Gas systems, both storage and continuous flow, suit homes with a gas connection and steady hot water demand. Electric systems are simple and cost-effective up front. Solar systems use roof collectors to cut running costs over the long term. Heat pump systems draw warmth from the air and are among the most efficient options available, and government incentives are sometimes available on the more efficient units. We will size the system to your household and budget and explain the running costs of each, so you can make the call with the full picture.

Repair or replace?

We will always give you honest advice here. If a repair is the smarter, cheaper option, we will tell you. If the unit is past it and you would only be throwing money at it, we will explain why a replacement makes more sense and what it will cost. Either way, the decision stays with you.
