Firstly, work out the number of people in your household and the type of gas hot water system used, then ask yourself a few questions.
Below are the various LPG gas water heater size guide factors:
-
Do they all take showers at the same general time of day?- Do they take showers simultaneously in different bathrooms?
- Do the showers have WELS 3 Star Rated Water Saving Shower Head NZ (maximum 9L/Min) or standard 18 to 25L/Min shower heads?
- Do some prefer baths, which use more hot water? Is the bath or spa oversized, requiring even more hot water?
- Do you run the washing machine, using hot or warm water, while people are showering?
- Is your dishwasher connected to the cold or hot water? If hot, do you use it while hot water is being used elsewhere?
- Do you live in a cold climate with cold incoming water?
Using WELS 3-star rated water-saving shower heads are a good idea.
It will save both water and energy whilst also reducing the size and cost of the gas hot water system.
Water saving shower heads really are a win-win-win, with less water, less energy and lower up front cost.
The LPG gas water heater NZ size guide is best determined by counting the number of simultaneously used shower heads and whether or not you have water saving shower heads, as your LPG gas water heater size guide.
