Water heater repair and replacement, often the same day
Most of our calls come down to one of three things: no hot water this morning, a tank that has started leaking, or hot water that runs out halfway through a shower. We repair, replace and service tank, tankless, indirect and heat pump water heaters across Connecticut and Massachusetts, and we will tell you when a flush fixes what looks like a failing heater.
What size do you actually need
Undersized and you run out mid-shower. Oversized and you pay to keep water hot that nobody uses. Two questions gets you close.
Water heater sizing guide
Common starting points used across the trade. Actual sizing comes from your usage pattern rather than headcount alone.
Tank sizing here is nominal capacity. What matters more is first hour rating, which accounts for how fast the unit reheats, and a well specified smaller tank can outperform a poorly specified larger one.
What we install and service
Most homes here have the first. The fourth is the one worth asking about, because it is the only category with meaningful rebate money behind it.
| Type | How it works | Suits | Worth knowing |
|---|---|---|---|
| Storage tank | Heats and holds a tank of water using gas, propane or electric elements. | Most homes. Simple, familiar, and the cheapest to install. | Standing losses keeping water hot around the clock. Lifespan is heavily affected by whether it was ever flushed. |
| Tankless | Heats water on demand as it flows through a heat exchanger. No storage. | Homes short on space, or with steady rather than simultaneous demand. | Output depends on temperature rise, and our winter inlet water is cold. Read the section below before committing. |
| Indirect | An insulated tank heated by your boiler rather than by its own burner. | Homes with a boiler, particularly where it already runs well. | Very efficient in heating season, and it makes the boiler responsible for hot water year round. |
| Heat pump | Moves heat from the surrounding air into the tank instead of generating it. | Basements with space and reasonable ambient temperature, replacing electric tanks. | Substantially cheaper to run than an electric element tank, and the one water heater category the state programs incentivize. |
If you currently have an electric tank, ask about the heat pump option. Both Energize CT and Mass Save offer incentives on heat pump water heaters, and they cost considerably less to run than resistance elements. They need adequate space and they cool the room they sit in, which in a basement is usually neutral or helpful. We check the space before recommending one, and we confirm the current incentive at quote rather than quoting a figure that may have moved.
Why tankless underdelivers in a New England winter
This is the single most common disappointment we are called to look at, and it is a sizing issue rather than a fault.
- Tankless output is not a fixed number. It is a flow rate at a given temperature rise, meaning how many degrees it has to lift the incoming water.
- Our inlet water is cold in winter. Ground temperature here drops a long way by February, so the unit has to work through a much bigger rise than the same model faces in a mild climate.
- Bigger rise means lower flow. A unit advertised at a comfortable gallons per minute figure delivers noticeably less when it is lifting water from winter temperatures to shower temperature.
- Which is why people say it works fine until January. Two showers that ran happily in September start competing in the middle of winter, and nothing has broken.
- The fix is specification, not repair. Sizing on winter inlet temperature rather than the headline rating, and being honest at quote about what two simultaneous showers will actually do.
- Hard water compounds it. Scale in the heat exchanger reduces output further, which is why tankless units need descaling on a schedule rather than when someone notices.
When it is worth fixing
Water heaters have a clearer end point than most equipment, because one particular failure is not repairable.
- Leaking from the tank body means replacement. The tank has corroded through and there is nothing to repair. Leaking from a fitting, valve or connection is usually a straightforward fix, so it is worth establishing which before panicking.
- Rusty or discolored hot water points at the tank interior or a spent anode rod, and on an older unit it usually means the end is close.
- Elements, thermostats, thermocouples, gas valves and igniters are all repairable parts at almost any age.
- Rumbling or popping noises are sediment, not failure. That is a flush, and it is worth doing before the sediment shortens the tank's life further.
- Past twelve to fifteen years on a tank, a significant repair is worth weighing against replacement, particularly if it has never been serviced.
- Running out faster than it used to is often sediment reducing effective capacity rather than a failing unit.
The one thing worth doing today. Look at the floor under and around the tank. A rusty ring, a stained pan or a damp patch means it has been weeping for a while, and a tank that is weeping is a tank that will eventually let go all at once. Finding out on your terms is very much better than finding out at midnight.
Three jobs that add years
A water heater will run without attention until it stops, which is exactly why so many fail early. There is very little to do, and almost nobody does it.
- Flush the tank. Sediment settles on the bottom, insulates the burner from the water above it, and makes the heater work harder while holding less. In an area with hard water this is the difference between a tank that reaches its expected life and one that does not.
- Inspect the anode rod. A sacrificial metal rod that corrodes so the tank does not. Once it is consumed, the tank starts corroding instead. Replacing a spent rod is inexpensive. Replacing a corroded tank is not.
- Test the temperature and pressure valve. A safety device that relieves excess pressure. It can seize shut over years of never operating, and a seized one on a heater that is overheating is genuinely dangerous.
Water heater questions
Tell us what you have
Tank or tankless, what fuel, roughly how old, and what it is doing. If it is leaking from the tank body, close the cold inlet and call rather than filling this in.
