Boiler Installation in Hempstead
Hempstead sits on elevated ground on the southern fringes of Gillingham, straddling the ME7 and ME8 postcodes. Unlike the densely built-up Medway towns below, Hempstead has a more spacious, semi-rural character, with views across the Medway Valley and easy access to the lanes leading toward Bredhurst and the Kent Downs.
Why Choose Advance Medway for Boiler Installation in Hempstead
Hempstead's homes tend to be larger than the Medway average, which means boiler selection is especially important. An undersized boiler in a four-bedroom detached house will struggle to heat the property adequately, while an oversized unit wastes energy and costs more to buy. Our engineers carry out a thorough heat-loss calculation during every home survey, taking into account the size of each room, insulation levels, window type, and how many bathrooms you have. The recommendation you receive is specific to your home, not a generic suggestion.
We are based in Medway and work in Hempstead regularly. Our Gas Safe registered engineers understand the properties in this area and the typical challenges they present, from original 1970s pipework configurations to the extended layouts that many homeowners have created over the decades.
Our quotes are fixed-price, provided in writing after a home survey, and include everything: the boiler, all materials, labour, old boiler removal, and full commissioning. There are no calls on installation day asking for more money because something unexpected came up. If we identify anything unusual during the survey, it is accounted for in the quote from the outset.
We also ensure your installation is fully documented. You receive your Benchmark certificate, we notify Building Control, and we register your warranty with the manufacturer before the job is considered complete.
Boiler Installation for Hempstead Properties
Hempstead's housing is predominantly from the 1970s and 1980s, but property sizes and subsequent modifications vary considerably.
Three-bedroom semi-detached houses: The standard family home in Hempstead. Most have one bathroom and one or two reception rooms. A modern combi boiler rated at 30-35kW is typically the best choice, providing efficient heating and instant hot water without the need for a separate cylinder. Many of these properties still have their original conventional systems, and converting to a combi is one of the most impactful upgrades a homeowner can make in terms of both energy savings and recovered storage space.
Four-bedroom detached houses (Hempstead Road, Capstone Road area): These larger properties are common in Hempstead and often have two or more bathrooms following extensions or conversions. When multiple bathrooms need hot water simultaneously, a system boiler with an unvented cylinder outperforms a combi boiler. The cylinder stores a significant volume of water at mains pressure, providing strong, consistent flow to all outlets. We recommend a cylinder size based on the number of bathrooms and the household's typical usage patterns.
Properties with conservatories and extensions: Many Hempstead homes have been extended over the years, adding conservatories, rear extensions, or loft conversions. These additions increase the total heating load. If your existing boiler was sized for the original property, it may be inadequate for the extended home. We calculate the heating requirement for the property as it stands today, including all extensions, to ensure the new boiler has sufficient output.
