What Water Heaters Do Plumbers Recommend?
What plumbers weigh when recommending a water heater, and why the answer depends more on your house than on the brand.
The honest answer is that it depends on the house
There is no single model that is right for everyone, and any plumber who names one before looking at your property is selling rather than advising. What experienced installers actually weigh is a short list, and none of it is brand loyalty.
Whether the house suits tank or tankless
Tankless units save space, deliver continuous hot water and generally last longer when maintained. They also need adequate gas supply, a vent route, and maintenance to reach that life.
Tank heaters are cheaper to install and tolerate hard water better in the short term, because sediment settles to the bottom rather than coating a heat exchanger. They recover slower. For a house with modest demand and no obvious place to run a new vent, a tank is often the sensible answer rather than the compromise.
How hard the water is
This is the local factor. Scale shortens the life of every water heater in the valley. On a tank it settles and gets flushed. On a tankless exchanger it insulates the surface the burner is heating. Either way, treating the water going in extends the life of whatever you install.
Serviceability
Can it be flushed without cutting pipework? Is the anode rod reachable? Will the next person be able to work on it? A unit that is awkward to service does not get serviced.
Capacity against actual use
Oversizing wastes money and space. Undersizing means a unit at full output constantly, which is how heaters fail early. The right size comes from fixture count and simultaneous demand.
What we would say on the phone
Tell us the age of the current heater, whether you have ever run out of hot water, whether there is any softening on the supply, and where the unit sits. That is usually enough to narrow it to two sensible options, and we will price both.
If you would rather we looked at it
