We offer free and impartial advice to help you select the most suitable boiler for your property based on your heating needs, budget, and long-term efficiency goals, while ensuring every boiler installation meets the highest standards of safety and performance. Our engineers are accredited by leading boiler manufacturers and come fully prepared with the right tools and expertise to install both gas and electric boilers with precision and care. With customer satisfaction and trust as our top priority, we also provide up to 10 years of manufacturer’s guarantee on new boiler installation, giving you complete peace of mind and lasting reliability.
With regular servicing, some older boiler models can continue to operate for many years, but eventually the cost of constant repairs can outweigh the benefits. If your boiler repair bills are stacking up and you don’t have a boiler cover plan, replacing your old boiler with a new, energy-efficient model may be the most cost-effective solution.
You may need a boiler replacement if your current system is beyond economical repair and it is cheaper to invest in a new unit, or if you are experiencing frequent issues that require multiple services and call-outs each year. Poor energy efficiency resulting in higher gas bills, or recurring problems such as leaks that cause costly repairs, are also strong indicators that a modern boiler replacement is the best option for long-term performance and savings.
Getting a new boiler is a major decision that impacts your comfort, energy bills, and long-term peace of mind. At AR Heating and Plumbing, we recommend choosing an A-rated boiler as it is more efficient, cost-effective, and designed to save you money while avoiding unnecessary problems in the future.
There are several main types of boilers to consider depending on your property and heating needs. Combi boilers are ideal for smaller homes that don’t require a separate water tank and need hot water on demand. Gas combi boilers are the most budget-friendly option for households connected to the gas supply, while oil combi boilers provide excellent efficiency for properties without gas but require an outdoor oil tank. LPG combi boilers are another alternative in the types of boilers available, offering efficiency levels similar to gas systems but with a separate tank.
Regular boilers are an excellent choice for homes where hot water is needed in multiple rooms at the same time. This type of boiler requires both a hot and cold water storage tank, usually placed in the loft, making it well-suited for larger households with higher water demands.
System boilers are commonly used in houses with more than one bathroom, as they are easier to install and do not require extra loft space. They can supply hot water to multiple taps at once without limitation, making them highly convenient for busy households. It is important to remember that all gas boilers must be installed by certified Gas Safe registered engineers, as an unqualified installation can invalidate your home insurance and the manufacturer’s warranty. With AR Heating and Plumbing, you can trust that every installation is carried out safely and to the highest professional standards.
