Tankless Water Heater Repair
A tankless unit tells you a lot before it quits. We test the gas or power, the water flow, the vent and the unit itself before we change any part. Have a tank instead? We handle water heater repair for tanks too. As a plumbing team just around the corner, we are close by when the hot water stops.

Is Tankless Right for Your Home?
A tankless heater can be a great fit, and sometimes a new tank is the better buy. Here is how the two compare in a Redford house, so you can decide before anyone quotes.
| Compare | Tank | Tankless |
|---|---|---|
| Hot water supply | A set amount, then it reheats | Steady, as long as you stay within what it can heat at once |
| In a Michigan winter | Reheats a little slower | Makes less hot water at once as the street water gets colder |
| Work to install | Usually like for like | Often a larger gas line, a wall vent, a drain and an outlet |
| Upkeep | A yearly drain and a valve test | A yearly flush in most homes with hard water |
| When the power is out | Many gas tanks still heat | No hot water without power |
| Wait at the far tap | About the same | About the same |
| Space | A tank on the floor | A box on the wall |
Usually a Good Fit
- Your tank is failing anyway
- You plan to stay in the home a long time
- The gas line and an outside wall are close by
- You want the floor space back
Often Better to Keep a Tank
- Your tank still works well
- You expect to move soon
- The gas line would need a long new run
- You need hot water through power outages
We tell you which way we would go in your house, and the price before work starts.
Types of Tankless Water Heaters
Most Redford homes that switch use a gas unit on the basement wall. The right type depends on your gas, your power and where the unit can vent.
Gas Condensing Units
The most common choice when a Redford home switches from a tank. A second heat exchanger pulls extra heat out of the exhaust, so the exhaust runs cool enough for a plastic vent out the side wall. That cooling makes a little acidic water, which runs to a floor drain.
Gas Non Condensing Units
A simpler gas unit with hotter exhaust. It needs a stainless steel vent made for it, but no condensate drain, which can help when there is no floor drain close by.
Electric Whole House Units
No gas line and no vent at all, so it can go almost anywhere. The catch is power. It draws a lot of current at once, and many older Redford homes need a larger electrical service before one can go in.
Point of Use Units
A small heater mounted right at one sink or bathroom. It gives quick hot water to a fixture far from the main heater, or to a new addition, without running a long hot water line.
Switching From a Tank to Tankless
Taking out a tank and hanging a tankless unit is more than a swap. We look at a few things first and put every one of them on the price before work starts.
- The gas meter and the pipe run
- An outside wall for the vent
- A drain and an outlet nearby
Gas Line Size
A tankless unit burns much more gas at once than a tank. The pipe from the meter often has to be larger.
Venting Through the Wall
Most units vent out a side wall. We pick a spot that keeps proper distance from windows, doors and the gas meter.
A Drain for the Condensate
Condensing units make a small stream of acidic water. It runs to a floor drain or a small pump.
The Chimney Your Furnace Still Uses
Taking the tank out can leave the furnace alone in the chimney. We check the draft and explain your options.
Power, Water Lines and Space
Gas units need an outlet for their controls and fan. We leave room around the unit so it can be serviced and flushed.
How a Tankless Installation Works
Four steps, and the full price comes first.
We Look and Show the Price
Gas, vent path, drain, power and water lines, then one price before any work.
We Prepare the Space
Shut off the gas, power and water, take out the old tank and run the new gas line and vent.
We Hang and Connect It
Water lines, gas, vent, drain and power, with room left to service it.
We Test and Show You
We fire it, check every joint and the vent, set the temperature and show you the controls.
Tankless Flushing and Descaling
Hard water leaves scale inside a tankless unit, and scale is the most common reason one starts to slow down or throw codes. A regular flush keeps it working.
Why Scale Builds Up
Minerals in the water stick to the hot parts inside. Over time that cuts flow and makes the unit work harder.
What a Flush Visit Covers
We shut the unit off, run a descaling solution through it, rinse it, clean the inlet screen and test it.
Signs It Is Due
A maintenance message on the display, hot water that slows down, or a unit that cuts out at low flow.
How Often
About once a year in most homes on hard water. A water softener can stretch that out.

Tankless Water Heater FAQs
Answers to the tankless questions Redford homeowners ask us most.
Is a tankless water heater worth it in Michigan?
It can be, when your tank is due anyway, you plan to stay, and the gas line and an outside wall are easy to reach. It is often not worth replacing a tank that still works. We look at your house and give you a straight answer, with the price before work starts.
Will a tankless keep up with my family in winter?
Water from the street is colder in winter, so a tankless unit makes less hot water at once. We size it for your coldest months and for the showers and appliances you run at the same time, so it keeps up in January as well as July.
Do I need a bigger gas line for a tankless water heater?
Often, yes. A tankless unit needs a lot of gas for a short time, and many older Redford homes have a gas line sized for a tank. We check the pipe from the meter and include any change in the price.
How often does a tankless water heater need flushing?
In most homes on hard water, about once a year. Homes with a water softener may go longer. If the unit shows a maintenance message or the hot water slows down, it is time.
Why does my tankless go hot then cold?
Usually the unit shut off for a moment and cold water slipped in before it fired again, or the flow dropped below what the unit needs to stay on. A clogged screen or scale can cause it too. We find which one it is.
What should I do when my tankless shows an error code?
Write the code down, turn the unit off and back on once, and check that the gas valve is open and the breaker is on. If the code comes back, stop resetting it and call us. If you smell gas, leave the house and call your gas company from outside.
Does a tankless water heater work when the power is out?
No. Gas units need power for their controls and fan, and electric units need power to heat. If outages are common for you, that is worth weighing before you switch.
Will I know the price before you start?
Yes. We check the unit or your setup first, then give you one price that includes the parts and any gas, vent or drain work. Nothing starts until you approve it.
