Gas and electric backup

Backup heating integrated with the solar loop and its control.

What it is

A tankless gas water heater warms water only at the moment of use. Cold water enters the unit, passes through a heat exchanger fired by gas burners, and leaves at the temperature you set. There is no stored volume, so there is no standby heat loss.

What is included

Technical survey and sizing report
Equipment with invoice and manufacturer warranty
Gas and plumbing materials
Gas line tightness test
Written handover and usage guidance

How it works

Site survey

We measure flow rate at each fixture, available water pressure and the gas type on site (LPG or natural gas).

Sizing

We calculate the capacity in litres per minute required for the number of fixtures that may run at the same time.

Installation

We run the gas and water lines, the flue for combustion gases and the electrical protection to code.

Commissioning

We set inlet gas pressure and outlet temperature, then test every fixture with you present.

Frequent questions

What capacity do I need?

It depends on how many fixtures can run simultaneously. One shower plus a sink usually calls for 15 to 20 litres per minute; homes with several bathrooms need a larger unit or more than one.

Is a flue really required?

Yes. Gas appliances produce combustion gases that must be vented outside through a correctly sized flue. Running one without proper venting is a carbon monoxide risk.

Will it work with low water pressure?

Tankless units need a minimum flow to fire up. Where pressure is low we pair the heater with a booster pump.
