HouseIt methodology
How HouseIt approaches hot water problems
Explain that household count is only a proxy; peak demand, recovery and equipment type change the answer. This cluster is organized by decision type—diagnosis, severity, sizing, repair-versus-replace or selection—so several long-tail questions can use one deeper engine rather than generating duplicate tools.
What information changes the result
Common decision inputs in this cluster include tank capacity, First Hour Rating, recovery, peak demand, household size, tankless, temperature rise, GPM. HouseIt asks for these progressively and keeps unknown values explicit.
Where an online check stops
Avoid gas/electrical servicing instructions.
