How much is Underfloor heating per m²?

by UFH1
We often get asked the question, “….how much is it per m²?” It is difficult to give an accurate answer without specifying the system to the exact requirements of each individual, for example: Our 1 port kit (£299.97+vat with thermostat) will cover: 20m² with 200mm pipe spacing 15m² with 150mm pipe spacing Or 10m² with 100mm pipe spacing (which is often used for conservatories, heat pump use etc.)

Water Underfloor Heating and Aluminium Spreader Plates

by UFH1
The use of aluminium ‘spreader plates’ is common in installing water underfloor heating to joisted floors.There are pros and cons of the use of spreader plates that should be considered for water underfloor heating:Pros1.    Easy to install for the novice installer as they set the pipe spacing2.    Lightweight – where biscuit mix can’t be used3.    Clean installation – less mess than biscuit mix4.    Quicker – generally faster to install than biscuit mix5.    Spread the heat evenly when used with insulation alone

Valli the elephants wall heating project.

by UFH1
We have supplied a wall heating system for a brand new, purpose designed home for Valli the Temple Elephant in Skandavale monestry. Valli has been with them since 1981, and for the last 30 years has been living next to the Shakti Temple with her keeper Swami Karuna. Progress on Valli the Temple Elephant’s barn was really quick. They built her new barn from hollow polystyrene bricks; they stack up on each other just like Lego, so they could build a whole wall in a day. They then pumped concrete into the bricks to make them strong. This system has been very successful, firstly because it is so quick to erect, and secondly because the polystyrene provides good insulation to keep Valli warm during the cold winter months.

Filling & Pressurising the UFH system

by UFH1
A test is performed at a pressure of 5 bar before flooring, screed or biscuit mix is laid to check for leaks and ensure the pipes are at their most expanded. This pressure is to be maintained until screed application is completed in order to ensure that any leaks are identified immediately and prevent the screed cracking later. 6 bar is a lot higher than a system would normally run.This action can be pressurised for testing purposes with mains water in most cases. REMEMBER: You must be extremely careful to avoid frost unless anti freeze has been added to the water. The flow from the mains tap to the filling point on the flow rail (red) of the manifold and the return/waste hose connected from the drain point of the return manifold (blue) to somewhere the return water can drain to.

How To Control The Room Temperature With Underfloor Heating

by Damien Wilkinson
All of our kits, with the exception of the single room thermostatic valve kit would require a separate room thermostat. The thermostatic valve kit measures the return water temperatures to open and close the mechanical valve.

Underfloor heating and the benefits

by Damien Wilkinson
Underfloor heating is fast becoming the preferred option to heat any home or workspace. More and more people are choosing to heat their homes with Underfloor heating as it is very low to run but remains high in comfort with huge environmental benefits.Underfloor heating radiates upwards from the floor space, heating other surfaces in the room which in turn then radiate secondary heat.  Floor draughts are eliminated and the heat in the room remains even. More traditional methods such as wall mounted radiators are known as convected heating which uses the air in a room as the mechanism to disperse heat into the whole room.  Using this type of conventional heating means that naturally the warmest part of a room is the ceiling and the coolest is the floor.  This is the opposite of Underfloor heating which is warmer underfoot and loss of heat is minimised.

Commissioning the System

by Damien Wilkinson
1. Check that all flow meters are open. Turn them anti-clockwise a couple of turns from closed2. Switch the programmer for zone 1 so that it is calling for heat, you should see a flame signal.3. There should be no actuators fitted on the manifold, the manifold pump should run and the zone valve should open (if one  is fitted).4. The boiler should fire up at this stage and the system should circulate water. Turn the flow meter on all circuits until the plastic indicator is around 1.5 (if using a boiler) or 1 for heat pump systems. The flow meter scale works down, so allowing more flow (like opening a tap) moves the red indictor down. As each are adjusted, some  you may have already set may alter slightly. We find that it’s best to alter in small increments.5. Turn the zone 1 room stat up to it’s highest temperature.

Underfloor Heating Costs

by Damien Wilkinson
Underfloor Heating is a beneficial eco-friendly heating solution that is more efficient and cheaper to run than other forms of heating such as radiators. It can be difficult to understand what is best for you and what the right price to pay should be. This is where we can help. At Underfloor Heating 1 we aim to find the product to best suit your needs that is particular to your property and at a price you won’t find anywhere else. Underfloor Heating 1 promise to beat any like for like quote. We always quote with a full itemised and quantified list of materials after obtaining the information specific to your property – not a generic quote-not all companies do this and beware any supplier that doesn’t! We only source products from the most reputable companies, such as Danfoss, Honeywell and Heatmiser. All of our products are from companies based in the UK or mainland Europe.

Underfloor Heating with a Ground or Air Source Heat Pump

by Damien Wilkinson
When using a heat pump to run underfloor heating we recommend that the underfloor heating pipe is laid at 100mm pipe spacing throughout the property. The main objective of having a heat pump is efficiency and installing the pipes at 100mm spacing maximises the efficiency. Air source heat pump manufacturers’ efficiency data is 7c air temperature and 35C flow temperature. Ground source heat pumps are the same although it is ground temperature and not air temp in the data and this flow temperature is generally only achieved with the pipes at 100mm pipe spacing. The COP (coefficient of performance – how efficient a heat pump is of converting electric into heat) of a heatpump is from these figures and installing the pipes at 200mm spacing would seriously reduce the COP.

Comparing Quotes

by Damien Wilkinson
If you have received a quote that appears to be cheaper than an UFH1 quote it could have significantly less equipment or equipment of lower quality than ours – for example another company specifying pipe 300mm spacing where we might put 200mm spacing, digital or dial thermostats etc., etc and we would either re-quote to match or point out where the differences are. We always specify our equipment with a full itemised list to do the job properly without cutting corners or quoting with vague equipment lists and usually find that ‘cheaper’ quotations fall short on equipment and/or quality and invariably the customer ends up having to fork out later for items “......that weren’t included”
