Can a tankless water heater be used for radiant floor heat?

The answer is yes, but it requires a lot of work. Tankless water heaters have been a proven technology with a long record of heating on-demand water heaters. But a few contractors have used them in the past for hydronic radiant heat, the information about finding the right system design can be hard. 

In some cases perfecting a system took a lot of trial and error. While the sun is out, you don’t need heat all day. So, you should use a programmed thermostat that will limit the temperature for your whole day according to your need.

Why tankless?

Well, the answer is straightforward. It takes a tiny place, and it usually measures 13 and a half inches by width, 23 inches by height and 9 inches in depth. It can also be mounted on any exterior wall type and will offer you endless hot water. Sound amazing, doesn’t it?

  • Temperature factor: Although there is the fact that the units are not frequently used for radiant heat, they are really ideal heat source for this premise as their output temperature can easily be fitted to the needs of the radiant heating system. Most of them provide up to 180-degree Fahrenheit, which is more than enough for 110-to-120-degree Fahrenheit is needed to run a radiant heating system. 
  • Economics: The economics of utilizing a tankless water heater is to supply both heating and DHW are also quite attractive. The system’s total cost falls around $5000, which is pretty much budget friendly.

How to select a tankless heater

It might be tricky to select a tankless heater because there are different types of them as they can be powered by propane, natural gas, or electricity. My suggestion will be for using a propane-powered heater as it is easy, and the electric-powered ones will not make it economically feasible.

  • Remote control: Try selecting a heater with are remote control as it makes the work easier for you. People usually set the temperature with a remote by 140 degrees coming out of the unit, and it is hot enough to meet your demands for wood and tile floors.
  • Sizing: The tankless water heater also comes in different sizes, so select the one which suits best for your space. And perfect sizing requires that you get an accurate picture of the home’s heating requirements. There is generally 5 type of low-flow faucet, dishwasher, shower head, clothes washer, and whirlpool tub.

BTU: Usually, a well-insulated brand-new house will not require more than 15 BTU per hour per sq foot. For 2000 sq feet, that will be 30000 BTU per hour. Even for the poorly insulated house, it shouldn’t require more than 60000 BTU per hour, which is okay because most of the units will have at least 150000 BTU outputs per hour.

Choosing the components 

Suppose you are willing to install a best boliler for radiant floor heating system with a combination of tankless water heater and radiant heat. In that case, you need a variety of fittings, switches, and pumps.

  • A vent pipe: it is really essential to use a vent pipe for the heater as it allows to have an intake water-filler screen and it helps for combustion and exhaust air.
  • Rinnai: The Rinnai will sell an optional plumbing kit which will contain two boiler drains, ball valves and a pressure-relief valve. If you buy it, it will provide to facilitate the purging system of air. And if you use mixing valves it will require a temperature gauge downstream for each of the valve and it will make you able to monitor the temperature of the water inside your system.
  • Programmable Thermostats: It is really essential to use programmable thermostats as the radiant floor systems are quite slow with their time. So if you set your timer with programmable thermostats, your work will become quite easy through-out your whole day.

What kind of flooring can you use with radiant flooring?

Well, surprisingly radiant floor system can be installed over a wide range of flooring. Some of its heating techniques and features cannot be used on all floor coverings.

The best type of flooring for radiant heating system are:

  • Ceramic tile.
  • Natural stone.
  • Laminate.
  • Porcelain tile.
  • Vinyl.

Best flooring featurettes

If you have to decide if the flooring is good or bad, you will probably look at its features, whether it is prone to water or heat, the floor’s thermal conductive nature, the thickness of the floor, the tendency to expand and contract, and many more.

  • The thicker floor coverings such as engineered wood or solid hardwood are like poor thermal bridges. 
  • The mineral-based floor coverings like stone and chiefly tile are really good thermal conductors.
  • Tile and stone don’t tend to contract or expand.
  • Floorings like solid hardwood are vulnerable to heat and moisture and can be easily damaged by them.
  • Natural stone, ceramic, porcelain are the best type of floorings as they encompass all four types of factors. Because the tile always feels colder than the other flooring types, the want of radiant heat against it is excellent.

Types of flooring and why it is good

  • Porcelain or ceramic tile: This type of flooring is ideal to use because it is thin and mineral-based, meaning that it conducts with heat very well. Moreover, it doesn’t contain any organic compounds to degrade if a hydronic system tends to leak water. It heats up really fast when the system turns on, and it also retains heat as soon as the system shuts off.
  • Natural stone flooring: It is quite similar to porcelain and ceramic tile, and any aggregate or natural stone is a perfect fit for a radiant heating system. It is safe, and it also retains heat for a more extended period of time. It is comparatively thicker than porcelain or ceramic, so it heats up slowly but never contracts and expands. Moreover, it cannot be degraded.
  • Laminate flooring: This type of flooring’s thinness is an advantage to the radiant heating system as it allows the heat to penetrate and dissipate. In hydronic systems, the laminate may get permanently destroyed if the moisture escapes. So you should take precautions to protect the floor.
  • Sheet or Vinyl Flooring: it is quite an excellent choice for a radiant heating system but you should check the manufacturer’s instructions on how much heat it can handle.

Type of floors that should not have radiant heat systems

  • We all know that rubber melts coming to high heat. So using rubber floors for the radiant heating system is a big no no.
  • Heat can also loosen or dry out the glue or adhesive and take off the carpeting. The flooring system that requires glue or adhesive is a poorer choice for radiant flooring system.
  • As concrete floors are relatively homogeneous, it is also a more inferior choice. However, it can be embedded in concrete floor slabs while subsequent top floor covers are added.

Does radiant heating system ruin hardwood floors?

If you use the wrong wood flooring, an improper installation method or the lack of proper humidity can be catastrophic. Apart from the conventional heating systems that will emit heat from the base of walls in the floors, the radiant system transfers heat directly up and under through the wood floorings at 80 degrees or higher temperatures. There is also another factor, like the comparison between electric vs gas boiler radiant heat, but this is whole another story. Let’s dive in the main topic.

How you should install radiant heating system over hardwood floors

  • You can install the radiant heat tubing directly under the wood subfloor below. This is the most famous installation method.
  • Another method is installing the hydronic radiant system within a plywood underlayment system directly over the existing concrete slab or over the existing wood subfloor.
  • The last method is installing the radiant system tubing within the concrete slab while you pour over the concrete.

Moisture testing

This is the most crucial factor if you have poured concrete slabs as they can contain a lot of water and should be allowed to cure for 60 days at least to 90 days before you can install any flooring. This applies to all concrete slabs, whether it is old or new. Here is an easy way to check the moisture. You should start by taping the edges of 3 foot by 3 foot square pieces of 4-7 mil plastic sheets in different areas of the slabs. Then you have to wait for 48 hours, and then you can look to see if there is any moisture building up under the sheets. If there are signs of moisture, you should wait a bit more to install the radiant heating systems.

FAQs About Radiant floor heating

What boiler is best for underfloor heating?

Answer: There is no such thing as the best boiler for underfloor heating as underfloor heating functions quite good with all types of modern condensing boilers.

What size of boiler do I need for in floor heat?

Answer: BTU requirements will tell you that you tend to need about 50 BTU per sq. foot in winter and 35 BTU per sq. foot in a moderate climate, and 20 BTU per sq. foot in summer.

Can you put radiant heat under wood floors?

Answer: Yes, you can. But be sure to check the moisture level before you install it.

What kind of fuel do I need to use for my heating system?

Answer: It does not matter what type of fuel you are using as long as it meets the BTU requirements, it is okay. But we highly recommend you to use propane or natural gas.

How frequent should I check my glycol system?

Answer: You should check it at least once a year so that you can ensure the pH levels have not risen or dropped below the recommended levels.

Can I air condition my home with radiant heating system?

Answer: It is highly advised not to do so simultaneously. The lower temperature will pull the heat from the air, and later it will be carried away in the tubing below the floor.

Radiant Floor Heating Buyer’s Guide: 

You will buy a radiant heating system to keep your home and yourself warm in the dead of winter. People who feel cold frequently are prone to buy a radiant heating system more because cold runs a shiver down your spine.

So here is a buying guide for you that covers what you should look for in a radiant heating system and what you shouldn’t. 

Here’s what:

There are plenty of radiant heating systems available in the market. Some of them are as follows:

  • Electric sub-floor heating: this type of heating system requires a network of electric cables for heating a floor. Brute heating is comparatively more expensive than geothermal heating, and most builders do not rely on large-scale installations. Somehow, electric heating is easier than geothermal, which makes it the perfect solution for a little upgrade.
  • Fluid Sub-Floor Heating: it is the most commonly installed heating system and preferred by all. And it is operated by the water-to-water geothermal heat pump. You can also install it with tankless water heaters as it has many benefits. It is really a perfect choice as a geothermal retrofit is way too expensive.
  • Water-to-water Geothermal Heat Pump: This one is eco-friendly and has an energy-efficient HVAC solution. It is one of the best ways to power up a radiant heating system.
  • Buffer Tank: Unless you use an electric tankless water heater, you might want to use a buffer tank as it is very useful. It can store heated water. For this the geothermal unit won’t have to operate itself every time you are warming the floors.
