Sizing for simultaneous showers in Surrey
A typical 4-bedroom South Surrey home with 3.5 baths needs 9–11 GPM at 60°F rise to handle two showers + dishwasher + laundry without temperature drop. That's the upper end of a single 199K BTU unit — we'll spec twin tankless units in parallel for 5+ baths or commercial-style demand.
Recirculation matters in big Surrey homes
Long pipe runs in 3,500+ sq ft Surrey homes mean 30–60 second hot-water lag without recirculation. The pump is included on bundled tankless rentals and uses about $2/month in electricity.
Why renting tankless wins for big Surrey families
Tankless units in hard-water Surrey need annual descaling — included free in your rental. Owners pay $200–$350 per descale, plus $1,800–$2,800 for an exchanger replacement if they skip it. The math favours renting on every large home.
