Use a Water Heater to Make Radiant Floor Heat Instead of a Boiler. Many people use a water heater instead of a boiler for radiant floor heat because it COSTS LESS. A hot water heater saves money when used in this way. A high quality water heater is more energy efficient and friendlier to the environment.
Because the slab installations will require less than 140 deg F water, it is safe to use a water heater to heat the radiant slabs. We will also be installing 2 separate water heaters; one to supply domestic hot water and a separate water heater to supply the radiant floor.
Secondly, can you put glycol in a hot water heater? Glycol, also called antifreeze, is an important compound that HVAC manufacturers use to protect hydronic heating systems in cold climates. Adding glycol to the water prevents such catastrophes from happening, but often compromises system performance. However, high-quality glycol can mitigate that risk.
Also, can I use a hot water heater to heat my house?
Heating the House With a Water Heater. While most combined systems start with the home’s boiler or heat pump, others use the water heater to produce heat for both tap water and the home. This is an option only if your house is very well sealed and well insulated, or if you live in a mild climate.
How do you heat a concrete floor with hot water?
The science behind radiant floor heating is quite simple: Tubes that circulate hot water or electrical heating elements are installed in the concrete slab when it’s poured, turning the thermal mass of the concrete into an inconspicuous radiator of warm, even heat.
What size tankless water heater do I need for radiant heat?
For example, if you are running 2 showers at the same time, you will need 5 gallons of hot water per minute from the tankless water heater. If you were running a shower and the washing machine at the same time, you would need 4.5 gallons per minute from the water heater.
Can tankless water heater heat whole house?
The answer is, you can. However, just because you can, doesn’t mean you should. It’s true that a tankless water heater can easily heat most single-family homes. It’s also true that a tankless water heater is smaller and less expensive than a boiler or a furnace.
What temperature should radiant heat water be?
85 – 125 °F
How do you control radiant floor heat?
Choose a thermostat designed specifically for radiant floor heating. Hardwood floor temperature limiting. Hardwood floors can dry out and suffer damage due to thermal expansion. Maintain a minimum floor temperature. Maintain comfort in rooms with large amounts of southern facing glass windows.
What is a good temp setting for radiant heat floor?
Cooling a Home That Has a Radiant Floor Heating System Radiant floor heating produces room temperatures very close to ideal: 75° at floor level, declining to 68° at eye level, then to 61° at the ceiling. Cooling, contrastingly, is best delivered through ductwork located near the ceiling of a room.
Can I use a tankless water heater for hydronic heating?
Hydronic heating: Just Add a Tankless Water Heater. A new hydronic air handler is designed specifically to work with a tankless water heater for high-efficiency space heating.
How long does radiant floor heating take to warm up?
The type of insulation and floor covering with underfloor heating can both affect the time the system takes to warm up. A wooden floor with good insulation can be expected to heat up within 30 to 60 minutes of being switched on.
Is the hot water tank connected to the furnace?
Tank-type water heaters: Tank water heaters have been the standard choice for heating water for many years. The heat source can be electricity, natural gas, propane or fuel oil. In an immersed coil installation, the hot water tank contains a heat exchanger that is connected to a furnace, boiler, or heat pump.
How do you heat a house with hot water?
Boilers are special-purpose water heaters. While furnaces carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house. The cooler water then returns to the boiler to be reheated.
What is the most efficient way to heat a home?
What are the most efficient home heating options? Solar heating. Geothermal heating. Wood heating. Heat pump (non-geothermal) Natural gas heating. Oil heating. Electric heating.
Do you need a hot water heater with a boiler?
Most people have a water heater – or in some homes a boiler is used to warm the water. A different type of boiler can heat the water to the point it turns into steam. The steam heats the water for the home but can also be circulated throughout the home and provide heat through radiators.
Are hot water heating systems efficient?
Less efficient: Heating with air is less efficient than heating with water. Reduced heat consistency: Forced air heat is not as consistent as steam or hot water heat. As a result, some rooms may be cooler or hotter than others. Inferior air quality: Since furnaces blow hot air, they also blow dust and allergens.
What is the most efficient heating system for a house?
Finding the Most Efficient Heating System: Boilers The third most efficient heating systems for homes are residential boilers. Boilers are less common in residential settings than heat pumps or furnaces. However, a boiler can still provide a good option for home heating.
