FAQs
How does a tankless water heater save energy compared to a traditional storage tank?
Traditional heaters keep 40-100 gallons of water hot 24/7, which means constant standby heat loss. A tankless unit heats water only when a tap opens, eliminating that standby loss. In typical Lancing homes this translates to 24–40 % less natural-gas or electricity use and noticeably lower utility bills, especially for households that use less than 40 gallons of hot water per day.
Will a tankless system supply enough hot water for my whole house?
Yes—if it is sized correctly. We calculate peak demand by adding the flow rates of fixtures you might run simultaneously (e.g., two showers + dishwasher ≈ 6 gpm). Then we match that flow to a model that can raise Lancing’s incoming water (about 50 °F in winter) to 120 °F. For large households we can install a high-capacity single unit or multiple smaller units in parallel to guarantee endless hot water everywhere.
What is involved in replacing my existing tank with a tankless unit?
Most retrofits take 4–6 hours. We drain and remove your old tank, mount the compact tankless unit on a wall, upsize the gas line or add a dedicated 240 V circuit (depending on gas or electric model), install new isolation valves and a condensate drain, and run fresh air-intake/vent lines through an exterior wall or roof. All work is carried out by our licensed, insured plumbers in compliance with Lancing building codes and manufacturer warranty requirements.
How much does installation typically cost and are there any rebates in Lancing?
Installed prices range from £1,400–£2,800 for gas units and £1,100–£2,000 for electric units, depending on capacity and venting complexity. Tennessee Valley Authority (TVA) customers may qualify for rebates up to £150 on ENERGY STAR® gas models, and the federal Energy Efficient Home Improvement Credit refunds 30 % of the unit plus labour (max £600) on your tax return. We complete all paperwork for you.
What maintenance does a tankless water heater require?
Annual maintenance keeps efficiency high. We descale the heat exchanger with food-grade vinegar to remove mineral build-up (hardness in Lancing averages 5–7 gpg), inspect the burner/elements, clean the intake filter, and verify venting and gas-pressure settings. The visit takes about an hour and costs far less than replacing a corroded storage tank.
How long will a tankless water heater last and what warranty do you offer?
With routine maintenance, tankless units last 20–25 years—roughly double the life of a conventional tank. Most leading brands back the heat exchanger for 12 years, parts for 5 years, and labour for 1 year. Our company extends labour coverage to 3 years at no extra charge, and we handle all warranty claims directly so you never have to deal with the manufacturer.
