Buying guide, Boilers:

There are three main boiler types:

  • 1. Combi boilers
  • 2. System boilers
  • 3. Regular boilers

Understanding each boiler type is important to identify the one suitable for your house. The prices listed do not include the installation fare.

Combi Boilers:

Combi boilers or combination boilers do not need a separate hot water cylinder, instead deliver water from one solid unit. They are easy to install and cheaper than the other models and therefore popular among customers. It is best suited for a smaller house with a wide range of kW outputs. The disadvantage includes the impossibility of the boiler to cope up with two showers or baths running simultaneously, not suitable for houses with many bathrooms.

The advantages of combi boilers include:

  • • Prompt and limitless hot water
  • • Energy efficient
  • • No cylinder or tanks essential
  • • Easier to install

System Boilers:

System boilers are ideal for houses with multiple bathrooms and great demand. They can provide a constant supply of water to all the units within a house. It requires a separate water cylinder for the storage of hot water, but they don’t need extra tanks. Like combi boilers, system boilers are easy to install energy-efficient to run.

The advantages of system boilers include:

  • • Provides hot water to multiple taps ideal for a large house
  • • installation quick and easy
  • • No need for separate tanks
  • • Solar thermal solutions

Regular Boilers:

Areas with low water pressure and homes with multiple bathrooms are ideal for regular boilers, also known as conventional or heat only boilers. They are best suited for homes with loft space and airing cupboard as they need a feed, expansion tank, and hot water cylinder. They provide a steady supply of hot water.

The advantages of regular boilers include:

  • • Perfect for larger houses with two or more bathrooms
  • • Simultaneously, provides water to multiple taps
  • • Suited for homes with a traditional central heating system
  • • Well-suited with solar thermal solutions

What do experts have to say?

It is significant to guarantee that a boiler’s Power Rating (or size) is just right;

• An undersized boiler might work too hard, and an oversized boiler may work below capacity. Both circumstances can lead to more fuel being used than needed.

• A heating engineer analyses the dimension of the boiler needed based on; heat loss, the number of rooms (Bedrooms, bathrooms, etc.), number of people in the property, number of radiators, showers, etc.

• Smaller houses and flats, with up to 10 radiators, will need a 24-25kw boiler. A 28-30kw would be installed for a medium to large 3-4 bed house with up to 15 radiators, and a 33-35kw and a 40kw would be for a large house with up to 20 radiators.

• In enormous properties spread over several floors over one boiler would be essential.

Boiler Manufacturer

• There are abundant boiler brands/manufacturers. Each one has an advertising strategy to trade their product. As a customer, it’s hard to tell which is “the best” or the right one for you.

• The hunt for “the best” is often problematic by heating engineers having a preferred boiler manufacturer that they like to install. They will each say that their proposal is better than the others.

• The cynical might suggest Heating Engineers prefer one brand over another because that is where they can make the most mark.

• Maybe one brand is less likely to become incorrect than another, one brand is easier to install than another, or that the engineer is just more familiar with a particular brand than another.

• A Gas Safe engineer will install a gas boiler of any brand, but it’s worth paying attention to why they endorse one brand over another. Quite often it will be because they can offer an extended warranty on that boiler brand.

Did You Know?

Is it possible to retrofit an old boiler to make it more energy efficient?

No. Standard Heating will not alter the original design of a boiler, because they are UL listed/labeled and should not be altered. However, in most cases, standard heating can replace a boiler with a more efficient unit. If your equipment is 20-30 years old, be prepared to think about replacing the boiler.


1.How Do I Know if My Boiler Is Economical?

If you’re buying a new boiler, or just trying to decide if you need one, how efficient it is will be a big part of your decision.

To find economical boilers, look for their ENERGY STAR rating. A well-rated boiler should run very efficiently, whereas a poorly rated model may be more cost-effective to replace in the long run.

You should find that all modern boilers are more economical when compared to older models.

  • How do I know if I’m getting a Good Deal on My Boiler?

Navigating price can be one of the most difficult parts of buying a boiler, and you want to make sure you get the best deal possible.

  • How much does a boiler flush cost?

The average power cost to flush your central heating system is typically around £300-£500 with the price depending on a few factors, such as the size of your home and the number of radiators in your house.

  • What happens if you overpressure your boiler?

Too little air in your expansion vessel and the pressure may become too high, resulting in the water coming out of your pressure relief valve. Too much air could result in an over the pressurized system, this could also result in water coming out from the pressure relief valve.

  • Do I need a power flush with a new boiler?

If you’re getting a new boiler installed, the building regulations recommend that a suitable cleanse is carried out before the installation. This can vary from a simple system flush with clean water to a powerful Power flush on more contaminated systems.


Biasi Riva Plus combi ERP boilers were built with quality in mind. It is impossible to achieve perfect boilers. There would be a significant difference to your bills when you replace a standard efficiency boiler with this model. The only difference in the models shown of Biasi Riva boilers is their output and flow rate. It is best to do some personal research to double-check what others are saying about the brand and model.
