Types of Residential Water Heaters. Most of us take our water heater for granted along with the luxury of having piping hot water dispensed from any tap in your home on demand. Many homeowners don't even think about their water heater until it causes problems. Water heaters are one of the hardest working appliances in any home, just think how many things would be impossible without the miracle of on-demand hot water like laundry washing dishes or showering. There are three distinct types of water heaters each with its own unique set of advantages and disadvantages. Solar Water Heater. Renewable solar energy is currently the only free option for water heaters. They are not appropriate for every home and situation but if the conditions are right, they are a fantastic investment. Conditions including the roof direction area or residence and size of the family must be met to qualify your home for solar power. The most common water heater type is a storage or tank water heater.

This stores a set amount of heated water in a holding tank. The tank water heater can be powered by electricity or gas and the supply of hot water is limited by the tank size. One major drawback is having to balance household activities to make sure there is an adequate hot water supply for each so that no one is stuck with a cold shower before the supply can replenish. Tankless Water Heater. Tankless or on-demand water heaters are growing in popularity largely due to their ability to produce an endless supply of hot water despite the amount of usage. These can be either a gas or electric similarly to tank water heaters. Tankless water heaters are also the most eco-friendly since they only heat water when it is needed. What Should The Water Temperature Be. No matter which style of water heater you choose for your home the safest and most recommended temperature is 120 degrees. In order to pass an inspection the temperature must be set at 120 degrees exactly, this is a code requirement. We always recommend this setting which is sufficient to kill any bacteria or germs that may reside in the water supply, but it is cool enough to avoid scalding which is much safer for children, pets and you too. If you absolutely must have a steaming hot shower please remember that setting the temperature at 125 or 130 degrees is still much safer than the maximum setting on your water heater.
