Can water heaters be used for space heating only?
While it works fine to use a water heater for space heating alone, it makes sense to design a dual purpose system — one that’s capable of heating domestic water as well. This approach makes sense because of lower operating costs and more efficient use of floor space.
Do hot water heaters need clearance?
Water heaters must be surrounded by a certain amount of clearance, or air space, to function properly and safely. A clearance area of 12 inches is required on all sides of a hot water heater. A certain amount of airflow is also required for proper combustion and ventilation.
Can you use a water heater for baseboard heat?
Do not try to use a water heater for heating your domestic and space heating. The baseboard is VERY thin wall & will not withstand the pressure used for domestic. Heating the House With a Water Heater.
What temperature should radiant heat water be?
85 F to 120 F
Radiant heating uses hot water – usually in the range of 85 F to 120 F – generated by a boiler, an air to water heat pump, a geothermal water to water heat pump, or a domestic hot water tank – to heat a building by using a large surface area with low temperature water.
Can you put glycol in a hot water heater?
Though they are sold primarily for domestic hot water, tankless heaters are actually well-suited for radiant heating, which operates at low temperatures compared with, for example, hot-water baseboard. However, with proper buffering and corrosion inhibitors a glycol can be used at high temperatures.
How far should a water heater be from the wall?
Can you put stuff next to water heater?
Store combustible materials within 18 inches of your water heater. Flammable items placed closer than that could potentially catch fire. Don’t … Store items that are prone to moisture damage such as books, papers, or magazines near the water heater.
What kind of heat do radiators use?
convection
The radiators are designed to heat the air in the room using convection to transfer heat from the radiators to the surrounding air. They do this by drawing cool air in at the bottom, warming the air as it passes over the radiator fins, and discharging the heated air at the top.
Are hot water heating systems efficient?
Investing in a modern boiler is definitely worth the money, as they are much more efficient than older models. In many cases, homeowners consider other options because their old boiler was not very reliable without realizing the efficiency of newer models.
Can a tankless hot water heater be used with an electric heater?
If the electric tankless can heat the water sufficiently there’s no advantage to putting it in series with an electric hot water heater, which would result in hot water from the tank being abandoned in the plumbing run between the two.
Can you place an electric on-demand hot water heater in?
For more information on this solutions, see Hot water circulation loops. You can plumb them in series and it will work, but it’s an expensive solution, especially if you end up having to upgrade your electric service to handle the massive peak draw of a tankless electric on-demand HW heater.
Can a hot water heater be used with radiant floor heating?
Single Purpose Systems. Either a hot water heater or a boiler handles all the heated water necessary to power the radiant floor heating needs. Meanwhile, a separate hot water heater takes care of the household hot water usage. Finally, a conventional furnace might be included to heat rooms that are not using radiant floor heating.
What’s the cheapest way to use a water heater?
Figure 2. A dedicated setup is the simplest, least expensive way to use a water heater for space heating. The author always uses a unit with side taps for easy installation. The pump is installed at the bottom to avoid air lock.
Can a water heater be used to heat a small space?
We wouldn’t rule out using an electric (or other type) of domestic water heater to heat a small space that is not served by the main building heating system, but using any water heater as the permanent and main source of building heating in a cold climate is generally a bad idea.
Why do you need an electric hot water heater?
The saving are extraordinary. The heater should be dedicated solely to heating due to slow recovery and desire to avoid mixing heating with domestic hot water. Otherwise heating water must be isolated by an approved heat exchanger. Thank you for your interesting comments, Steve.
Which is the best type of hot water heater?
The right kind of tank-style water heater makes a great source of heat for any kind of hot water space heating system. Simple, economical, easy to maintain and reliable. Check out this detailed technical tutorial on how to make it happen. Loading…
Can a tankless water heater be used to heat the House?
The output in Btu of a heater large enough to supply a home’s domestic hot-water needs is typically sufficient to meet its heating needs as well. If the heating circulators happen to be running at the same time as the domestic hot water, the temperature in the heating loops may drop slightly.
