Warm Air Units

Advanced technology has enabled warm air units to become highly sophisticated pieces of equipment. They provide reliable, controllable heating that is economical to run. As a renewable energy, warm air heating has many ecological benefits. Some systems are even eligible for financial assistance through the Renewable Heat Incentive scheme. Warm air systems are not always practical for every property, but to find out if your home is suitable, give No1PHD a call and one of our local heating experts will discuss the options and give you a quote completely free of charge.

How Do Warm Air Units Work?

A warm air unit draws in air from the interior and exterior of your home. The air moves through an internal heat exchanger that is powered by a fuel such as gas. The air is heated until it reaches the temperature set by the thermostat. It is then driven by a fan into a network of ducts or pipes distributed throughout the property. The warm air enters each room through vents covered by grilles in the walls, floors or ceilings. A warm air system is one of the fastest methods of heating a home.

Advantages of Warm Air Units

Through technology, warm air units are no longer associated with the faults of the early, primitive systems of the 1960s and 1970s, which were frequently blamed for aggravating respiratory conditions such as asthma. Current models can have the benefit of optional filters that generally operate at ten minute intervals to remove from the air approximately 95% of bacteria, allergens and debris such as, pet hair, dust and pollen. The air quality within your home should be consistently clean and fresh. Air is a lightweight medium that requires very little heating. It enables the unit to use a lower temperature range yet warms it much faster than alternative forms of heating and results in running costs that are often around 18% lower. Some systems can also provide hot water when integrated with a combination boiler. Correctly installed, the vents are unobtrusive and internal fans are virtually noise-free.

  • Reduced carbon emissions
  • Optional filters effectively remove 95% of air impurities
  • Lifespan of at least twenty-five years
  • Some units compatible with a combination boiler
  • Aesthetically pleasing, occupying minimal wall space

Different Types of Warm Air Units

Air Source Heat Pump

This is an extremely versatile air conditioning style system. It can be in use throughout every season either warming or cooling the air to ensure your home always has a comfortable, ambient temperature. It can easily convert external temperatures that are as low as -20 degrees Celsius.

Ground Source Heat Pump

The most complex warm air unit is the ground source heat pump. It’s installed in the earth outside your home to a depth of around four feet where the temperature stabilises at almost twelve degrees Celsius. Air drawn into the unit is warmed or cooled to comply with the thermostat setting before being pumped through the system’s network of ducts. It’s an ideal system for new home improvements as the installation is lengthier and is more complicated. When our heating engineers can coordinate the installation with our other range of services such as kitchen refurbishment, it becomes a much easier, faster process.

Gas Systems

Warm air units that use a gas flame to heat the incoming air are sturdy and reliable. They are frequently installed by the No1PHD heating engineers in large households with high heating demands. It’s an economic system due to gas energy being less expensive than electricity. Even further household economies can be made if the system is compatible with a combination boiler.

Electric Systems

This warm air unit uses an electric resistance heater to warm the air. It usually incurs higher running costs due to the expense of electricity. It is often more suitable for a compact home with relatively few heating demands.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
