1. If you have a fault once the system is up and running, the first thing to check is the flow rate in the flow meters. Make sure they are set between 1.5L/min and 2L/min for boiler use and 1L/min for heat pump use. If there is no reading (the red indicator is at the top) nothing is flowing around the loop.2. Then take off your actuator heads, if you then get a flow or your system then works you know it is an electrical problem. If after taking all the actuators off you still have problems then it will be a flow fault

We answer your questions about laying underfloor heating onto existing floors.

Dust allergies give many people a stuffy or runny nose and itchy and watery, red eyes. They can also make it difficult to breathe triggering asthma symptoms, such as tightness in the chest, shortness of breath, coughing and wheezing etc.

There are two types of underfloor heating: gas-powered (wet) underfloor heating and electric underfloor heating.  In wet underfloor heating systems, heat is distributed around the house via thin pipes laid under the floor. These pipes carry hot water around the home so that it can release its heat through the floor and therefore warm the rooms where the underfloor heating system is installed. The water is heated in the main boiler of the home. In cases where the boiler supplying hot water for the household is gas powered (as is the case in most UK households) this type of heating system is known as wet underfloor heating. An electric underfloor heating system, on the other hand, uses electric wires fitted beneath the floor to provide heat. When an electric current is passed through the wires, they become hot and that heat is transferred through the floor to the room above.

One of the most frequent questions we get asked from customers wishing to retro-fit underfloor heating (UFH) is what is best/most cost effective, excavate the existing floor or add a board system? Whilst costs can vary hugely by area, tradesman etc., we've compiled a list of comparative costs for each type of UFH install and labour etc. on a typical approx. 75m2 project:

Let UFH1 help you choose the right underfloor heating controls for your project.

Underfloor heating as you may well know usually consists of warm water in plastic pipe embedded in a concrete floor, in-between floor joists or in some form of specialist board. All of these make it very important for the UFH to be installed with care and professionalism to ensure it’s a ‘fit and forget’ system.Done correctly, UFH should give excellent heat output and efficiency - more so than radiators – and it requires no more maintenance than any other heating. The old adage ‘what happens when it goes wrong?’ should simply not apply to UFH; however it must be designed and installed correctly to ensure peace of mind.

Preparing your floor for underfloor heating is highly important, failing to prepare your floor thoroughly may cause problems in the system later down the line. This guide is for solid floors only

Probably one of the most frequently asked question we get is "what type of flooring can I have with underfloor heating". It's a good question as there are a lot of variables to consider with each flooring option. Simply put, we would rank the types of flooring that are most commonly used in the following order:1.    Tiles/natural stone – Porcelain, ceramic, granite, marble, travertine etc.2.    Vinyl – Karndean, Amtico etc.3.    Engineered wood – usually 14mm-18mm4.    Solid wood – 22mm max5.    Carpet – max 2.5 tog ratingBut why are some more popular than others? There are a lot of variables to consider when choosing flooring to lay over your underfloor heating, such as thermal conductivity, insulation properties, style, etc. Lets break it down into those 5 types of flooring.
