Is it worth getting underfloor heating?
In our opinion the answer to that is a resounding ‘Yes”. The benefits of having a gentle, ambient, low energy, heating system, that is allergy friendly, low maintenance and also allows you to move your furniture around wherever you want to, speaks for itself.
How hot does the floor get?
The water that flows through the underfloor pipework never goes over 50°C because it can damage the slab. So whilst the floor will be comfortably warm it won’t be hot.
With under floor heating, it is not how warm the floor get it’s about the overall air temperature inside the house, with our systems designed to hold the temperature at a comfortable 21°C.
Do underfloor heating systems leak?
Once the pipework is covered with concrete it is very well protected. On the off chance one of the pipes get punctured during installation, the builder will know about it instantly as we fill and pressurise the pipes at the time of our installation. We have the ability to repair it using a special tool designed to clamp and fix the puncture.
All our pipe work is also covered by a 25-year warranty.
How much does it cost to run underfloor heating?
It is very difficult to answer this question as costs depends on how much you are paying for your gas/electricity supply, what temperature you have it programmed to run and the weather outside. If it is 4 degrees outside the heating will have to work harder to hold the temperature than if it’s 12 degrees outside.
Whilst hydronic is more expensive to install than a comparable sized ducted system it’s long-term running costs are less. It also stays warmer for longer because the heated water in the system holds the heat.
How long does in slab heating take to heat up?
If you have underfloor slab heating – Normally about 4 hours. It depends on how cold the slab is to start with and what the weather is doing outside.
If you have underfloor in screed heating – Normally about 1 hour. Due to the lesser amount of concrete the hydronic heating must heat.
How long does hydronic underfloor heating last?
Nissl Eichert only uses, what we consider to be the best equipment in the market. This ensures that our customers get the best value for money for their hydronic heating systems. The beauty of in slab heating is that once it’s installed, so long as it’s kept in use and maintained properly, the pipes inside the slab will last for multiple decades. Our current pipe work all comes with a 25-year warranty.
The boilers and heat pumps will need to be replaced and upgraded as the technology constantly evolves, improves and changes with the new models being so much more efficient than the older ones.
Can underfloor heating be zoned?
Yes, it can be. This needs to be discussed and designed early in the process of designing the system. A lot of our clients will have the main living area zoned independently to the bedrooms. Please be aware we normally cannot zone individual rooms. For each zone you need different controllers and a minimum surface area to be heated.
What flooring materials are compatible with hydronic underfloor heating?
Polished concrete, tiles, carpet and natural stones are all 100% compatible with underfloor hydronic heating with some engineered timbers also suitable. However natural wood is to be avoided due to the fact it stops the heat coming through and can split and crack due to the expansion and contraction.
Please discuss flooring options with the designer of your system, they will advise on what they would recommend and what to avoid.
Can I put natural wooden flooring over the underfloor hydronic heating?
No, that is the one type of floor covering you can’t put over slab heating for a couple of reasons. Wood is one of natures’ best insulators, so it works against the heat coming through from the slab. It also expands and contracts too much.
If you have your heart set on parquetry flooring, you may want to consider radiator panels as an alternative. If using an engineered timber floor please inform your flooring provider that the floor covering and it’s adhesive, will be on top of a hydronic heated slab.
What is a manifold?
A manifold is a metal framework that sits low to the ground on the concrete slab. It is the distribution point for the hot water coming into the house form the boiler/heat pump and it has all the flow and return pipes for the hydronic under floor heating centralised.
A manifold is usually located inside the bottom of a cupboard as we do need access to this in the future when servicing the equipment.
