Heating your Water
Direct, Indirect, or Tankless Water Heater?
One of the most important and expensive pieces of equipment in your home is your water heater! Water heaters can account for almost 25% of your home's energy consumption, making this a very important piece of equipment that shouldn't be neglected.
We recommend that you replace your water heater every 7-9 years, this time frame can vary based on use and the level to which it was maintained. If you are in need of a new water heater you have several options. The most popular is the storage tank water heater. This can range from 30 gallon to over 100 gallon capacity and can operate directly or indirectly. The larger tanks will accommodate more people in your home and more appliances using hot water, like dishwashers and washing machines. An indirect storage tank is heated through the boiler, this requires your boiler to get up to temperature to heat the water properly.
A direct fired water heater can be heated by propane, oil, or natural gas and has it's own burner. These types of water heaters are traditionally the most energy efficient. They are more energy efficient than an indirect water heater because it heats the water itself. Indirect water heaters rely on the furnace or boiler to supply the heat needed for the water.
On-demand water heaters heat your water on the spot. These are usually referred to as tankless water heaters as there is no need for the water to stored. A tankless water heater can be heated by propane or natural gas, or oil if a tankless coil is installed in your boiler. While these water heaters heat water only when called upon, they do not perform as well if more than one person or appliance is calling for hot water. They are excellent for 1-2 person homes while storage tank water heaters provide the best value for larger families.
