New boiler Horsham

A-rated new boilers and boiler replacements near Southwater

Your boiler is the heart of your heating system in Southwater or Horsham. Energy studies suggest that your boiler is responsible for 60 per cent of your energy bills, so it makes sense to aim for your boiler to be as energy efficient as possible.

The older your boiler is, the more inefficient it is likely to be. Our new boilers are over 90 per cent efficient. They are likely to reduce your energy consumption by a third, saving hundreds of pounds on your energy bills. Current regulations state that new boilers must be condensing boilers. These boilers can capture the gas generated by burning fuels and use it to heat the cold water entering the system. They are designed to recover more heat before it is lost.

Your new boiler will be compatible with smart heating controls, so it can make everyday life more straightforward because you can manage and customise your heating from your smartphone or tablet.

New boilers are also quieter and offer greater flexibility because the latest combi boilers can be wall-hung or hidden in a kitchen cupboard.

A manufacturer’s guarantee will accompany your new boiler, and we can offer extended guarantees of boiler models from Valliant and Worcester Bosch. This is a great way to provide an additional layer of security and make your property more appealing.

Case Study: Landlord boiler replacement in Horsham

Are you a landlord looking for cost-effective and efficient boiler installations or servicing? Surrey Gas is a small team of Gas Safe-accredited boiler engineers with a wealth of experience in the trade. One of our customers, a landlord with a portfolio of rental properties who we have worked with for many years, called to say that his tenants were experiencing problems with their boiler and had no heating and hot water.

Our engineers went to the property the same day. It is a multiple occupancy flat in Horsham, and we carried out a number of checks. The boiler was 11 years old, and the repairs – due to failed parts – would cost over £500. We advised our customer that a new boiler would be cheaper to run and more reliable. We are accredited by Valliant and Worcester Bosch, but we supply and install boilers from all major brands.

We advised about the best new boilers, and the landlord decided to opt for a Worcester Bosch Greenstar 4000. This boiler is one of the manufacturer’s mid-range models and is ideal for small and medium homes.

The Results

The fact that our customer’s tenants were without heating and hot water made this job a top priority for us. We returned 36 hours later and removed the old boiler and installed the new one whilst working around two of the tenants who were working from home. As part of the job, we flushed the system and upgraded the controls to give the tenants more accurate control over their heating and money saving.

They were happy to learn that the new boiler would be far more energy efficient than the older model, and we showed them how to operate it.

Our customer said: “I am delighted with the service I received from Surrey Gas. As a landlord, I need a boiler company that I can rely on to be responsive, and in the past, they have always provided prompt service and looked after the maintenance of the boilers in my properties. This is the first time they have installed a new boiler for me, but I am really happy with the results. The quotes were accurate with no hidden costs, and the tenants said the installation was seamless. I would wholeheartedly recommend Surrey Gas to others.”

Any challenges?

No, there were no challenges apart from ensuring the boiler installation was completed as quickly as possible to ensure that the tenants were not left without heating and hot water for long.
