Gas hot water heater

Also known as tankless or ‘on demand’ water heaters, continuous flow systems heat water only when it’s needed. There's no hot water cylinder, so no energy is wasted from unused hot water left cooling in the tank.

How it works

As soon as the hot tap is turned on, the system ignites and heats water to a pre-set temperature. It does so via a powerful heat exchanger that transfers heat from the gas-fired burner to the water.

Why it’s good


  • Never run out of hot water
  • Pay only for the hot water you use
  • Digital controller gives you control over temperature and supply
  • Options for LPG and natural gas available

Is it safe?

There are no major health or safety risks associated with continuous flow water heaters. The system can be set to deliver hot water at a safe temperature of 55º.

How much will it cost?
