FAQs
How much can I save on energy bills with a tankless water heater?
In most Manchester homes, a high-efficiency condensing tankless unit can cut hot-water energy use by 20–40 %. Storage cylinders keep 40–80 litres of water hot 24/7, while a tankless model only fires when you open a tap. For a typical family spending £350–£400 a year on gas for water heating, the switch generally trims £70–£150 off the annual bill, depending on usage patterns and the price of gas or electricity.
Are tankless water heaters suitable for Manchester’s climate and water quality?
Yes. Modern units have built-in frost protection down to about –20 °C, so even in a detached property’s unheated garage they cope with a North-West winter. Greater Manchester’s water is classed as moderately soft, which means limescale build-up is far slower than in the South-East. That extends heat-exchanger life and reduces maintenance frequency compared with hard-water areas.
What size (flow rate) tankless water heater do I need for my household?
Sizing is based on the number of fixtures you may run simultaneously. Count 8–10 L min for a shower, 4–6 L min for a basin and 6–8 L min for a kitchen sink. A two-bathroom family home that might run two showers at once usually needs a 20–24 L min, 30–35 kW gas unit or an 18 kW electric model. Our installer performs a free on-site survey to measure incoming cold-water temperature (which affects output) and advise the right specification.
Will I need to upgrade my gas or electrical service?
Gas units above 30 kW often require a 22 mm supply pipe rather than the older 15 mm line. We pressure-test your existing pipework and quote for upsizing if necessary. Electric tankless heaters typically need a 3-phase 400 V supply or a dedicated 80-100 amp circuit—something most UK homes lack—so for whole-house applications gas remains the more practical choice. We assess your meter and consumer unit during the survey.
How long does installation take and will my water be off?
A straight swap from a combi or vented cylinder to a wall-hung tankless unit takes about one day. You’ll lose hot water for 4–6 hours, but we schedule the change-over so you still have cold water for toilets and washing. If flueing, gas pipe upgrades or removal of a loft tank are involved, allow up to two days. Our team disposes of the old cylinder and fully commissions the new system before leaving.
What ongoing maintenance is required and do you service in Manchester?
All manufacturers mandate an annual service to keep the warranty valid. We descale the heat exchanger, check combustion, clean the inlet filter, update firmware and log flue-gas readings. In Manchester’s soft-to-moderate water this takes around one hour and costs £90–£110. For heavier use (hair salons, cafés) we recommend a chemical flush every two years. Our Gas Safe-registered engineers cover all M and SK postcodes and offer same-day call-outs for fault codes or leaks.
