Radiant heating systems come with many benefits when it comes to heating your home. Is it widely accepted as the most comfortable type of heating system. Delivering consistent warmth while being silent and not forcing air, it provides a very natural feeling heat and a gently ambient heat form for the entire house.

Compared to other single-source heating options that only heat a single room, radiator central heating systems are highly efficient and will heat your whole house consistently. A fully controllable thermostat gives you the flexibility to heat the rooms you want as you wish, with different settings in different rooms at different times of the day.

Another benefit of radiator heating is the efficiency of the systems. Radiator heating is one of the most efficient ways to heat your home. Water transfers heat at a much higher rate than air, which means that radiators can heat up a room in a manner of minutes, unlike air which takes longer. And a big factor is that performance of the radiator is maintained regardless of the temperature outside, unlike with other heaters.

One type of underfloor heating system you can use when putting together a central heating system is the heat pump underfloor heating system. Why is this system the one to go for?

Heat pump underfloor heating systems are extremely efficient systems. The reason for this is that heat pump use electricity to move heat, not make it, which makes them much for efficient than other systems such as gas or solar. Heat pumps are a low temperature heat source which makes them perfect for an underfloor heating system because underfloor heating systems run a low temperatures. Heat pump systems are very versatile, they can work anywhere, unlike solar systems which require a certain amount of sunlight to warm the water. They can be incorporated in almost any underfloor heating system, allowing them to be used in all home and buildings where an underfloor heating system is required.

Are you having an issue with your radiator? You will be pleased to know that it may be possible to fix the problem without a professional. What can you do to fix a radiator that isn’t working?

Check the lock shield.

If one of your radiators are not working, first thing you need to do is make sure that the lock shield is open. To the left you will see an image of what a lock shield typically looks like, it will be found under a cap next to the radiator. To make sure it is open, turn it all the way you can anti-clockwise.

If this has not solved your problem, you may have air in your radiator. A common symptom of air in the radiator is if you can feel that both flow and return pipes are hot as well as the bottom of the radiator, but the top is cold. This is always a sign of air stuck in the radiator. To solve this, you will need to bleed the radiator. It is highly recommended that you turn the boiler and pump off before trying to bleed the radiator.

Bleeding the radiator.

To bleed the radiator, make sure both pump and boiler are off and both radiator valves are open. Put a small towel under the bleeder valve or screw and open the screw to let the air out. Once water is coming out and no more bubbles, let it run for a few seconds and the close the valve/screw.

If this does not fix your problem, the next place to look is the Thermostatic Radiator Valve (TRV). The valve could be stuck shut . If this is the problem, it may need to be replaced.

Checking the TRV.

The first thing you need to do is make sure that it is fully turned on. Now you need to remove the TRV head. How this is done will depend on the valve, some have a screw on collar, some will have a black plastic lug which you need to pop a screw driver into and turn to remove. There may also be other ways. Once the top is off, you should be able to see the valve. Now you can push down on the pin to see if it is stuck or not. If it moves up and down, it is not stuck. Do not hit it with a hammer, especially if you have an older pin type head. What you need to do is get a set of long nose pliers and wiggle the pin to try to release it. If you are successful, the pin should come back up. If it has returned, try to push down on the head again and see if it returns. If not, you need a new TRV.

We are currently have a special on a central heating system for all Aucklanders.

The Bosch Condensing Hydronic Heat Boiler is an excellent system for home heating, providing extremely efficient low cost heating to your home. By utilising condensing technology to recover waste heat, it then expells this through the flue system of the built in non condensing boiler. This system makes the Bosch unit 90% energy efficient, one of the highest rated system available. The boiler also includes a 37 kW combi boiler, combining heating and hot water supply all into one unit.

We are offing this unit for as little as $2999 installed to all Auckland homes! If you would like to take advantage of this special, call us today on 0508 446 892. But get in quick, supply is limited!

Brilliant German made system introduced into New Zealand about 10-15 years ago. Very compact and can easily supply efficient heat to smaller  and midsize floor areas. Laos ideal with for combination systems where low temperature and high temperature systems need to be combined. For example radiators and underfloor heating. Laing is a unique and one of kind system that allows you to create indirect systems at unbeatable prices. The image above represents a n UFH system we serviced this week. Part of the inspection is to ensure all valves, circuits, electrical and expansion tank are working correctly and safely.

Central Heating in NZ  offer affordable repair and servicing services for any size Laing underfloor heating systems. If your system needs a repair or maintenance give us a ring and speak to the pros!

These days there are many heating systems available which you can choose from to heat your home. Among these is the central heating system.

Firstly, what is a central heating system? Central heating systems are system which typically use hot air, gas or electricity to provide heat to multiple rooms within a building, such as a home or office. Systems such as heat pumps or passive heat (such as solar radiation) can also be used.

What are the benefits of a central heating system? Central heating systems provide many benefits to a living space including:

• Highly efficient heat supply
• Low cost
• Rooms can have individual thermostat control
• One heating unit can be used instead of multiple in separate rooms
• The gas, oil or solid fuel being consumed is removed from the heated space (creating a safer environment)

Central heating systems are incredibly efficient heating systems which can heat your home at very low cost. Talk to us today about a central heating system for your home.
