Intergas HRE OV Regular Boiler

Intergas HRE OV

The Intergas HRE OV Regular is an ideal replacement for existing open vent boilers.

Designed to supply your home with warmth and comfort, the Intergas HRE OV Regular is a fully modulating boiler that makes sure no valuable energy is wasted. It comes in three heat outputs to suit most homes and is best suited to properties with an existing open vent boiler or a traditional heating system. By using this boiler, you can save money on your energy bills, limit your carbon footprint and do your bit for the environment.

How Much Does this Boiler Cost?

It will depend on whether you require the 18kW, 23kW or 27kW model and the highest output model tends to be the most expensive of the three. What we can tell you is that the Intergas HRE OV Regular typically costs between £800 and £950, including VAT. These prices don’t include the fitting cost, so you need to shop around as installation prices can vary from £500 to £1,500. The easiest way to compare prices and find the best deal is to get a fixed-priced quote from a range of local and national installers. 

How will I know if this Boiler is Suitable for My Home?

The Intergas HRE OV is a regular boiler, also known as a conventional or heat only boiler. This type of boiler requires a feed and expansion tank in the loft, as well as a water storage cylinder to provide both heating and hot water. The boiler is therefore perfect for homes with an existing regular boiler and these additional components. If you don’t currently own this type of boiler, a combi or system boiler will probably be a better option for your home. 

If you’re interested in the Intergas HRE OV Regular, you must figure out whether you need the 18kW, 23kW or 27kW model. Choosing the right size boiler is extremely important as there is no one-size-fits-all solution, so make sure you ask a reputable heating engineer to help you pick the best size for your home.

Is it a High Efficiency Boiler?

Yes, it is. The Intergas HRE OV Regular has an A rating for efficiency and it has been endorsed by the Energy Saving Trust, proving that the boiler meets the energy performance requirements to help you save both energy and money. This fully modulating boiler ensures economical operation and can automatically adjust the capacity to match your needs so that no energy is wasted.

Does this Boiler have a Good Range of Controls and Features?

The boiler has a control panel with all the usual features, such as a digital clock and buttons that let you set the temperature and reset the system. It’s fitted with a modulating control that adjusts the power in line with the required heat and it has a built-in frost thermostat to protect the boiler against frost damage. There is no air pressure switch and it has almost no standby losses, plus it comes with vertical and horizontal flue options. The Intergas HRE OV Regular also comes complete with a reliable heat exchanger with a 10-year warranty.

How long is the Warranty on this Boiler?
