How to control your heating this winter

With Christmas approaching, it’s the time of year we all start wondering: “how do I control my heating?”

Knowing your heating controls and how to operate them correctly will help you to keep your home at a comfortable temperature without wasting energy, costing a fortune or costing the Earth.

We answer your most frequently asked questions to help you confidently control your heating this winter.

How should I use my thermostat/s?

A simple tip is to remember that a thermostat is simply a switch that turns the heating on and off depending on the room temperature. Thermostats are commonly mistaken for a throttle, turned up high with the misconception that this will speed up the heating of your home. By correctly using your thermostat, setting it at the desired temperature, you avoid wasting energy by accidentally overheating your home.

What temperature should I set my thermostat to?

This varies from person-to-person, but generally 21°C is the ideal temperature for living areas. Bedrooms tend to be set slightly cooler at 18°C.

The temperature you choose can make a big difference to both the comfort of your home and your bank balance – by turning your room thermostats down by just 1 degree could save £80-£85 and 340kg – 350kg CO2 per year according to the Energy Savings Trust.

Should I leave my heating on all day?

This can depend on the heating system you have installed and your lifestyle. Generally, for a comfortable and welcoming home that isn’t wasting energy, you should set a timer.

When setting up your timer, use a cold evening and time how long it takes for the heating to warm up to a comfortable temperature – this is the warm up time. Then switch the system off, and time how long it takes the system to cool down to cold – this is the cool down time. With these two figures you can now work out an accurate timing schedule for the heating system. If you know it takes 30 minutes to reach 21°C, you can set the heating to come on half an hour before you arrive home from work or get out of bed.

If this sounds a little too complicated, you may choose to install a more sophisticated thermostat like Nu-Heat’s neoStat. Many modern stats like the neo now come with self-learning functions and are able to automatically adjust when your heating switches on throughout the year for optimum performance.

Does it really matter where my thermostat is located?

Yes, definitely. Room thermostats should be placed in a location where they can receive a free flow of air from the room to read an accurate temperature. It’s important that they are not blocked by items such as curtains, pictures, or furniture. You should also make sure that they are not near any additional heat sources, like a log burner, or draughts.

Do I need to update or replace my heating controls?

At a bare minimum, a heating system should have a boiler thermostat, programmer/timer, and room thermostats (or thermostatic radiator valves with radiators). Providing you have all of these items installed it’s generally just a case of understanding how to effectively use them.

If your existing controls are over 14 years old it may pay to upgrade them. Newer, more precise controls could well offer greater savings and comfort levels.

What is the most efficient way to control my underfloor heating?

Warm water underfloor heating is highly efficient and you can improve this efficiency even further by making sure you are controlling the system in the best possible way.

There are two main types of underfloor heating and they are controlled in very different ways:

Screed underfloor heating

In a screed system, the heating tube is embedded beneath a thick layer of screed. It will have a high thermal mass, so you can expect it to take some time to warm. Because of this, screed underfloor heating should be turned on around an hour earlier than an equivalent radiator system. A screed underfloor heating system will also hold heat well, meaning that longer “off” periods are possible.

For an efficient system and quick response times, set your programmable room thermostats to 16°C in “off” periods. This will result in a quicker warm up time as the heating system needs to supply less energy.

Low profile and retrofit systems

Retrofit underfloor heating systems, like LoPro™, or solutions where the heating tube is close to the floor surface will heat up quicker than a traditional screed system.

If you have a low profile system with good heat outputs you can control your underfloor heating in the same way that you would a radiator system.

Top tips for heating your kitchen

Of all the rooms in your home, the design of your kitchen is perhaps the most crucial to get right. In addition to choosing fixtures and fittings that reflect your taste and suit how you will use the room, it is also important to install an efficient heating system to create a warm and cosy space.

Warm water underfloor heating (UFH) is an invisible heating system that is ideal for kitchens where wall space is often at a premium, particularly if you have bi-fold doors.

UFH works best when the interior design is reflected in the UFH design – read our top tips for getting the most from UFH in your kitchen.

Consider your kitchen units

Good UFH design will take into account the position of your fixed and portable kitchen units.

Warm water UFH works by pumping a controlled flow of warm water through tubing embedded in the floor, warming the surface of the floor above it. This emits an even, gentle heat into the room. Anything that is directly above the embedded tubing – including your kitchen units – will be warmed by the UFH. This doesn’t cause a problem if you are not storing food in your kitchen units, and a tube layout that runs around fixed units (rather than under them) will ensure that the temperature of designated food storage areas is not affected.

However, if you have portable units and islands, or are considering changing the layout of your kitchen in the future, it is best to run the UFH tubing across the whole floor. This avoids the risk of resulting cold spots where your units used to be. The base of your kitchen units can easily be insulated to ensure that their contents are not warmed.

Choose compatible floor coverings

Hard floor coverings such as tiles and engineered timber are a stylish and practical choice in kitchen areas, but they can feel cold underfoot if they are not paired with a suitable heating system. UFH delivers an efficient, even heat across the entire floor, and is compatible with a wide range of floor coverings, including engineered timber, tiles, vinyl, laminate and polished concrete. A floor temperature sensor can limit the heat output from the floor to protect sensitive floor coverings.

Renovation projects

If you are planning to retrofit UFH into your existing kitchen, you’ll be pleased to hear that there is no need to dig up your floor! UFH can be fitted directly on top of an existing floor to minimise disruption to your fixtures and fittings.
Make sure you consider the full height build-up, including any structural decks that may need to be laid over the UFH before your floor coverings can be fitted. Nu-Heat’s LoPro™10 UFH adds just 15mm height build-up and floor coverings can be laid directly on top.

Whether you are extending, renovating or building from scratch, contact us on 01404 540650 to discuss the best UFH solution for your property.

Expansion joints & underfloor heating

When the screed over an underfloor heating system dries, you can expect it to expand and contract with the changes in temperature. In order to protect the floor, and prevent it from cracking, expansion joints should be fitted during installation.

Expansion joints UFH

What are they?

An expansion joint can be easily made out of Nu-Heat’s edge insulation or any other flexible material, cutting holes around the tube position.

The purpose of an expansion joint is to allow movement to happen within the screed floor, releasing any stress build up to avoid cracking.

When should I use expansion joints?

For both liquid anhydrite and sand and cement screeds, expansion joints should be placed in high stress areas – these are where large areas are in contact with smaller ones e.g. in L or T shaped rooms. Expansion strips should also be used where UFH tube passes through doorways.

In sand and cement screed floors, expansion joints should be fitted when the surface area of the screed is great than 40m² or within any single length of screed greater than 8m.

What is expansion sleeving?

Expansion sleeving also prevents any stresses from building up in the tube to avoid damage. It should be placed around any piece of UFH tube that runs through an expansion joint (300mm either side).
