Can underfloor heating pipes be joined?
We offer a range of underfloor heating pipe repair fittings the same fitting can also be used for joining two underfloor heating pipes together when pipework needs extending.
How do you extend underfloor heating?
There are two basic methods of adding capacity to a underfloor heating system: Using existing manifolds. Adding new manifolds.
Can you add onto underfloor heating?
Traditionally underfloor heating has only been installed at the new-build stage, but with the introduction of a range of retrofit solutions, it is now possible to install UFH into existing houses.
How far apart should the pipes be on underfloor heating?
Pipe spacing The most common spacing between each pipe run is 200mm. However, this will vary in some instances both wider and narrower spacing, based on the heat loss of the area. Heat loss will be adversely affected by large areas of glazing, or poor insulation values.
Can you join 2 underfloor heating mats together?
Yup, you can connect 2 or more mats in parallel to cover any area.
Why is my underfloor heating so expensive to run?
Room Insulation & W/m² Used It's not just floor insulation you need to consider when fitting an underfloor heating system. Inadequate room insulation is a primary cause of higher running costs, because draughty rooms lose heat much quicker than rooms with insulation up to modern standards.
Is underfloor heating cheaper to run than radiators?
Underfloor heating is more eco friendly than using radiators and uses less energy, meaning they cost much less in the long run! As long as you have installed it properly, you could save about 25% of the energy you would use with a radiator, and up to 40% when running from a heat pump.
Can you overlap underfloor heating?
Remember, never overlap the heating mats as this will cause localised overheating, leading to eventual failure and invalidation of the manufacturer's guarantee. The thermostat sensor must be positioned centrally between the heating cable loops – see the Thermostat and Floor Sensor section below.
Does underfloor heating increase electricity bills?
Underfloor heating is not likely to save you much money, even when it comes to your energy bills. On average it is estimated that underfloor heating will save you around twenty pounds per year on gas or electricity. This means it is definitely a choice made for reasons other than budget.
Is it cheaper to leave underfloor heating on all the time?
Basically, your home will heat up to a comfortable temperature faster. So, whilst it won't necessarily be cheaper to leave your underfloor heating on for a sustained period initially, it could lead to long-term savings.
Should you run underfloor heating on all the time?
It is advised that in the depths of winter, an underfloor heating system should be kept on at all times. Although it should be at different temperatures depending on usage and activity in the house. This is because underfloor heating can take two to three hours to warm up, so it is best to not completely turn it off.
How much space should be between pipes?
The basic principle for deciding the spacing the pipes running parallel to each other is: Center to Center Spacing = 1/2 O.D of the bigger size pipe flange + Insulation thickness of bigger size pipe (if applicable) + 25 mm + 1/2 O.D of the smaller size pipe + Insulation thickness of smaller size pipe(if applicable).
Can you extend underfloor heating cable?
Don't ever cut or shorten the heating cable! Every ThermoSphere electric underfloor heating mat and cable is designed to a specific resistance rating – this is what creates the heat. If the heating cable is cut or lengthened, that resistance rating changes and the cable can become damaged, or not heat up sufficiently.
Can you extend underfloor heating sensor cable?
If the floor probe or power supply cables are too short upon installation, both of them can be extended and must be altered by a qualified and certified electrician only.
Can you adjust underfloor heating?
The floor temperature can be adjusted by choosing appropriate pipe spacing between 10 and 30 cm (depending on the pipe diameter, heat loss in the room or the type of floor), as well as balancing the flow in individual loops.
Does underfloor heating need an expansion vessel?
This guideline should help you to decide what expansion vessel to use, – 1000 m of pipe needs a 4l vessel. So if the underfloor heating system has 3000 m of pipe, then the underfloor heating system will need a 12l expansion vessel.
How to repair a leak in an underfloor heating pipe
When you suspect or indeed confirm you have an underfloor water leak in one of your heating system pipes, the instinctive reaction is how to stop it immediately, mindful of the potential damage that an untreated invisible leak could cause. There are two different ways you can tackle this challenge.
New sealant perfects leak repairs in underfloor heating pipes
A new water based sealant with high viscosity, non clogging and non corrosive components is proving an amazing sealing product. Designed and manufactured specifically for the Construction and Automotive Industries by C Tec, this leak repair solution has been creating quite a stir in the DIY fraternity as well.
What is the difference between PEX and AL-PEX?
The key difference between PEX & AL-PEX pipe is that AL-PEX is WRAS approved, meaning that you can use the same pipe through-out your home or project, including pipe for potable (drinking) water, leading to a more efficient project, as any excess piping can be used elsewhere in a project.
How hot can PEX pipes get?
PEX & AL-PEX pipes can withstand up to 95ºC, while PERT can only withstand 60ºC. Water underfloor systems reach 65ºC if their mixing valves are turned right up, so choosing PEX or AL-PEX gives you peace of mind that your system will keep going strong, even at capacity.
What is the phone number for Snug Underfloor Heating?
The Snug Underfloor Heating Technical Support Team are always happy to help and advise the best pipe to use for your project requirements, simply call us on 01772 761333 or email [email protected].
How long is a sandbox?
They’re available in lengths of between 75m and 500m, ideal for bigger projects.
Is AL-PEX pipe WRAS approved?
As discussed above, AL-PEX pipe is WRAS approved and can be used for potable water.
How to repair damaged underfloor heating pipe
Clients and builders often ask me “What happens if an underfloor heating pipe gets damaged during construction?”
Step 3 – Prepare the pipe
Next we have to ream the ends of the pipe with a pipe reamer to get smooth edges. This allows our fitting to form a tight seal on the end of the pipe.
Step 4 – Cut a section of clean pipe
The next step is to cut a section of fresh PEX pipe to replace the section that we cut out. If the damaged section was only small, then we might be able to repair it with a single fitting. If it’s too long then we need a new section of pipe.
Step 5 – Attach fittings
First we push the nuts over the end of pipe, then push the olives and fittings onto the end of the pipe.
Step 7 – Pressure Test
The next step is to pressure test the new fitting to make sure it’s properly sealed. We have to refill the underfloor pipework with water at the manifold and check that it’s holding pressure.
Step 8 – Seal
It’s good practice to wrap the repaired fitting in a layer of waterproof tape. This keeps the concrete off the metal, which helps prevent any corrosion.
