I have two bathrooms, a bath and a shower, and the water heater is a gas plus a water return device

Two bathrooms recommend considering a volumetric central hot water system. If the volume is about 150L, it should be fine.

Both gas and electricity are available on the market.

The recirculating water system is embedded during the renovation, so that there is hot water as soon as the faucet is opened.

If you are not sure, you can consult a decoration company, called: instant hot water system.

The basic cost should be within 10,000 yuan. Much more comfortable than a combination of two water heaters.

After a few years of use, I feel that it is more comfortable to use electricity.

It seems that there is a constant temperature of the gas now, but I have never used it.

If you can, I recommend using solar energy and instant heating to have solved the problem of large water consumption and timely hot water.

Personal suggestion is still the gas + return water solution Your gas water heater gas should be installed in the kitchen or balcony. The water return device can solve the problem of water consumption, first of all, the power is relatively large, and the energy consumption of the special line is still relatively expensive compared with gas. Personally, I don't think one water heater can solve the problem, don't install 2.

One more is one more source of failure.
