Our best boiler Selection process

As a minimum standard to make it into our Best Boilers 2017 list we require the following attributes to be met. These attributes are quite stringent, however these attributes ensure the home owner achieves a good and efficient boiler at the minimum:

 

  • Criteria for boiler selection for homeowners.
  • Warranty minimum 5 years.
  • Modulating / OpenTherm Controls are available (see the new BoilerPlus Standards)
  • Ability to range rate the boiler
  • Must contain an ERP Pump
  • Minimum modulation ration of 5 to 1

 

RAM

In order to choose the best boilers, we apply an engineering principle one of our clients (a former engineer) taught us whilst installing his boiler. The principle is known as RAM. Each product has a RAM score. The RAM score is made up of a combination of three system attributes. Sometime all three attributes are not necessary for a product to be reliable and good Ie if a product has high reliability and high availability, then maintainability does not need to be high for most applications. RAM attibutes are as follows:

Reliability – A products that has a high statistical result of performing well as intended
Availability – A product or its parts being easily available so that it perform the main use
Maintainability – A product’s ability of being repaired when it fails.

Efficiency

All boilers sold in the European union require an energy label. All boilers now sold in the UK are minimum ‘A’ Rated. Some boilers are however more efficient in there long term running even in this category. Important to note is the overal system efficiency of the heating system. Please read the article ‘Heating System Efficiency’ to gain insight into what makes a heating system highly efficient.

 

Limitations of this article:

We would like to bring to your attention that also we have chosen these boilers on good standards, sometimes the boilers that need to be chosen may be more specialised than any boiler in this list. Therefore in these situations only an experienced heating professional can specify specialist systems. This article is however applicable to the majority of the population even though some home owners/landlords may decide to choose lower quality boilers due to their budgets.
