Boiler Installation FAQs
How long does it take to complete standard boiler installations in Horsham?
The time to install new boilers varies. Simple installations may take one day, while more complex jobs, like switching to a different type of boiler or making modifications, could take up to three days. The type of boiler plays a factor, as well. For example, combi boilers take less time to install compared to conventional boilers. After assessing your situation, the heating engineer will provide the expected cost and duration of the entire process.
How do I know which type of boiler best fits my home?
Choosing the right boiler can be tricky, especially with the variety of modern options available on the market today. However, the perfect boiler for your home depends on several key factors, such as your specific needs, budget, and the size of your property.
For instance, for small to medium-sized homes, a combi boiler is an excellent choice. This is because combination boilers are both energy-efficient and space-saving, as they provide hot water and heating from a single unit.
In contrast, regular or conventional boilers, while reliable, require more space. This is due to the fact that they have two separate tanks for hot and cold water. Therefore, these types are better suited for larger homes with traditional hot water systems and greater heating needs.
Similarly, system boilers are ideal for homes with multiple bathrooms. They are effective in meeting higher demand because they use hot water cylinders to store and supply heated water.
Condensing boilers are highly efficient, too, capturing and reusing heat from exhaust gases that would otherwise be lost, thereby reducing energy waste. These come in various sizes so this can also be a great choice.
After conducting a free property survey, our boiler engineers will guide you in selecting the perfect boiler for your home in Horsham.
How do I avoid the need for frequent boiler repairs on my newly installed unit?
Although it does not totally remove the possibility of a breakdown, a regular servicing is a cost-effective preventative maintenance that can help you avoid having to book too many emergency boiler repairs. Here in Rowlen, we offer an annual boiler service to help you keep your boiler’s performance in its optimum efficiency and reduce its chances of unexpected breakdowns, which can be a real hassle especially when it happens during the colder months.
Tucking away cash every year for your boiler’s maintenance needs is a small price to pay in exchange of your home’s warmth, safety, and comfort. When you book for our annual servicing, our heating engineers can easily identify potential issues before they become major problems, helping you avoid the horrors of costly repairs.
Moreover, a regular boiler servicing is highly recommended by most boiler manufacturers to keep your warranty valid.
