Avon's houses, fuels and where heaters sit
Avon is a town of more than 18,000 people in Hartford County, with West Hartford and Bloomfield to the east, Simsbury to the north, Canton to the west and Farmington to the south. Much of the housing dates from the postwar decades: colonials, capes, ranches and split-levels on larger lots, with some older farmhouses, condominium complexes and newer subdivisions mixed in.
Natural gas serves some streets and not others, so the fuel at your address is the first thing to establish. Where gas is missing, oil, propane and electric fill the gap, and plenty of homes are heated by an oil boiler. In those, the simplest way to make hot water, for decades, was a coil built into the boiler itself, which is why so many Avon basements have no separate tank at all.
Heaters generally sit in a basement utility area near the boiler or furnace, in a closet in condos, or in a finished lower level in newer houses. Water is mixed: parts of town are on a public supply, while private wells are common on other roads. A well matters to the heater because the water arrives cold in every season.
Cold well water and slow recovery
Well water arrives cold all year, so every gallon needs more heat before it reaches the tap. A tank recovers more slowly, a tankless unit delivers less hot water at full temperature, and a coil falls behind when several taps run together.
That is why a heater that seemed fine in autumn can run short in January. Sizing for a well home starts with the coldest water of the year, not the average one. Tell the installer about the well and about your busiest morning, and the recommendation will follow from those two facts.
Why the boiler runs in summer just to make hot water
With a coil, the boiler has to stay hot all year, because it is the heater. Households hear it fire in July, even with no heating needed, and turning the boiler off for the summer simply ends the hot water.
If you would rather the boiler rested, there are two routes. An indirect tank beside the boiler heats only when called on, and a standalone heater runs separately from the boiler altogether. We make no claims about fuel saving or running costs, only about how each setup behaves. See indirect water heater installation.
Describe what the boiler does in July and we will identify the setup.
Flushing a tank: what it achieves and what it cannot undo
Flushing clears loose sediment, keeps noise down and protects elements and burners. It cannot reverse hardened crust at the bottom of the tank, a spent anode rod or corrosion already under way, and on a tank that has been neglected for a long time it carries some risk.
For that reason a technician decides whether a given tank is a flushing candidate, and does the work. On a well, flushing at a sensible interval matters more, since more sediment arrives. This is not a household job, and we do not suggest steps to try. See flushing and maintenance.
Expansion tanks and thermal expansion in a closed system
Water expands as it heats. In a closed system, such as a well with a check valve or a house with a device on the main, that extra volume is trapped, and pressure climbs until the relief valve drips.
An expansion tank gives the water somewhere to go. It holds a cushion of air behind a diaphragm, set to match your house pressure. Over time the diaphragm can fail and the tank waterlog, so a heater that dripped, then stopped, then dripped again may need its expansion tank checked. See expansion tank installation.
Where does the hot water come from in an Avon house?
Four setups cover most homes. A standalone tank has its own burner or elements. A tankless wall unit stores nothing. An indirect tank stands beside the boiler, linked by two pipes, with no burner of its own. A coil sits inside the boiler, so there is no tank to find.
Look without touching anything. If you cannot find a tank and the boiler fires in summer, you almost certainly have a coil. Knowing which you have changes the questions we ask, and it is worth a photo before you call.

Water heater repair and replacement questions in Avon
Why does my boiler run in the summer?
If a coil in the boiler makes your hot water, the boiler has to stay hot all year to supply it. That is normal for the setup. If you would like the boiler to rest in summer, an indirect tank or a separate heater can take over.
Can a tankless coil be cleaned instead of replaced?
Sometimes. If the coil is only restricted by scale, a technician may be able to clear it. If it leaks or has corroded through, cleaning will not help. A visit shows which applies, and we explain the replacement options when cleaning is not enough.
Would an indirect tank give us more hot water than the coil?
Usually, yes. A coil heats water as it flows and can fall behind when several taps run, while an indirect stores a full tank of hot water ready to use. The gain depends on the tank size, so the installer will size it with you.
We are replacing our boiler. What happens to the hot water?
If the hot water comes from a coil, a new boiler without one leaves you with none, so decide before the boiler work. Options include an indirect tank or a standalone heater. Call us early and we will coordinate on the hot water side.
Is an oil-fired water heater still a sensible choice?
Where oil is already delivered and no gas runs on the street, it can be. It needs fuel storage and suitable venting, and the unit recovers quickly. We will explain how it compares with propane or electric at your address and leave the choice to you.
My oil burner has stopped. Should I try to restart it myself?
No. Repeated restarts can make a fault worse, and burner work belongs to a heating specialist, not us. If the problem is cold taps, we can look at the hot water side. Describe what the boiler and the taps are doing when you call.
Is natural gas available for water heaters here?
On some Avon streets, not on others. Whether gas passes your door is a question for the gas utility, which can confirm it for your address. Meanwhile, oil, propane and electric are all workable, and the local installers will explain which suits your house.
Do you cover the whole of Avon?
Yes. The local installers work throughout the town, including homes on town water and those with wells. Give us your address and we will connect you with an installer who serves your part of Avon.
Our Avon house has an oil boiler and a well. What should we tell you?
Say that you are on a well, whether the boiler makes the hot water through a coil or indirect tank, and how the hot water has been behaving, especially in winter. A photo of the boiler and any tank helps us prepare.
