What Makes Hydronic Floor Heating Such A Great Choice?
It is a well-known fact that the best way to heat an area is from the floor, simply because warm air rises. However, there are many other great reasons to choose hydronic floor heating:
It’s incredibly safe as no heating elements are exposed to children or pets.
It’s healthy and does not dry out or move the air around.
It has the lowest running costs or any heating system. With new advancements in solar, gas and even wood burner options, water is now very cost-effective to heat.
The hydronic floor heating system offers remotely programmable thermostats in order to program each room’s required temperature. Select 4 different time slots, 7 days a week, from your phone, anywhere in the world!
Did you know that hydronic floor heating can be up to 60 percent cheaper to run than electric?
The rapid price increases of energy in South Africa have made running conventional electrical floor heating unfeasible.
In addition, the actual electrical capacity being allocated to new homes is being significantly reduced which makes warming your home a challenge – in addition to the high energy costs of conventional heating.
Hydronic underfloor heating addresses this problem perfectly, using water to transfer heat into the required rooms. Special pipes, made locally by our preferred partner Warmup, are laid in the floor screeds during construction. Hot water is then pumped through the pipes warming the floors, producing a combination of radiant and conductive heat.
The saving in running costs depends on the system used to heat the water:
- Heat pumps
- Solar collectors
- Wood burners
- Gas burners, or
- Or a combination of the above
Indeed, each heat source has its pros and cons when comparing the initial layout versus running costs.
Heating System and Insulation Requirements
- Hydronic underfloor heating can be installed under most floor types. In the event of sensitive floor types, a sensor is installed in the floor and a temperature limit is set.
- Underfloor insulation must be installed and the higher the “R-value” the better.
- This insulation (up to 30mm) can either be installed below the concrete slab at the early stage or it can be laid directly under the piping and screed.
- Marmox by Warmup is an exceptionally effective insulation with a high R-value for a very thin layer of space (10-12mm).
- Perlite is another product that can be used. It is a compound that is mixed with a screed which can be applied before the pipes are laid.
- Building and ceiling insulation is imperative in every heating system and should be installed throughout the house.
- Ceiling insulation is most important and should be 100mm thick or more, preferably of the more effective “powder type”.
- Double-glazing, although costly to install, has a significant effect in the overall insulation properties of a building. It will substantially reduce the running costs of any heating and cooling system in a building.
