Question:
Why does the water temperature during showers often fluctuate between hot and cold? Is it because low incoming water pressure prevents the water heater from igniting and heating properly, or because the pressure drops after heating? What causes this issue? Can installing a booster pump solve it, and where should it be installed to ensure a comfortable hot shower in winter for the whole family?
Ans:
- Fluctuating shower temperature is often caused by insufficient water pressure. Whether you are using a solar water heater, an electric water heater, or a gas water heater, installing a booster pump can help improve and stabilize this issue.
- Installation recommendation for solar water heaters and electric water heaters:
It is suggested to install a dedicated hot-water booster pump at the outlet of the solar water heater or electric heater to increase hot water pressure to bathrooms on each floor. - Installation recommendation for gas water heaters (no dedicated hot-water pump required):
3-1: Install a booster pump at the main water supply source (water tank) to increase pressure for the entire household, ensuring stable water supply for the gas water heater as well.
3-2: Install a booster pump at the inlet of the gas water heater to provide pressure specifically to the unit. (In this case, it is recommended to install a check valve and pressure relief valve at the inlet to prevent hot water backflow.)
