Baseboard Hot Water System

I have a baseboard hot water heating system. When the faucet for hot water is turned on, it does not come out very fast. I need some guidance as to what possibly could be the problem and how costly it might be to fix it.
Appreciate any help or if you need further information.
Thanks so much.

Re: Baseboard Hot Water System


In most cases the hot tap water is separate from the baseboard heating system.

The exception would be if you have a boiler that has what is known as a "domestic coil" inside it---this type of boiler has a copper coil inside the boiler that supplies the hot tap water.

Could you provide the brand & model # of the boiler; do you have a boiler along with a gas or electric heater next to the boiler??

How long has this condition been going on?? Do you have a lot of minerals in your drinking water (hard water)??

Please post back.

Re: Baseboard Hot Water System

Our house was built on ledge here in Maine, and we have extremely hard water.
The boiler is a New Yorker Model #AP590, and it does have a coil. This is the only source of heat and hot water supplier.
These symptoms, started out roughly 6 months ago, and has slowly gotten to this point, does take quite a while to fill up the kitchen sink, or tub.
I absolutely love this site. I have browsed through many of the postings and have learned quite a bit of information.
Thanks for responding to my posting.

Re: Baseboard Hot Water System


First try cleaning the little screw-on aerators where the water comes out of the faucet---you probably have one on the kitchen sink & probably the bathroom sink---the tub sink may or may not have one.

Take a piece of black electrical tape, or scotch tape & wrap it around the aerator so you don't mar the chrome finish---then take a pliers & unscrew the aerator.

There is a little screen filter inside that often gets clogged up with hard water crud; clean thoroughly--make a note of the sequence you remove the screen, washer, etc., & replace the same way after cleaning.

If cleaning the aerators doesn't cure the problem you will have to call a boiler service person to look at the boiler coil.

Quite often in hard water areas the copper coil inside the boiler (domestic coil) that heats the hot tap water get clogged up with calcium deposits & restricts the flow of hot water to the faucets.

The service people have chemicals they can run thru the coil to try & open it up---the charge may be $100 to $200 for the service.

If it does turn out to be calcium buildup & the chemicals can't open it, the coil can be replaced with a new coil for ~$300 to $500.

In both cases the problem can re-occur & you may need water softener equipment installed where the well water or city water comes into your house.

Some people opt to have an indirect hot water heater installed as a heat-exchanger zone to the boiler (cost ~$1000); this eliminates the problems with the small coil inside the boiler & provides all the hot water you would need for baths, showers, etc.

If you don't have a service person now, consult the Yellow Pages under "Boilers-Repairing & Cleaning" or call your fuel supply dealer.

Please let us know how you make out in solving this problem.

Re: Baseboard Hot Water System

Response to JacktheShack....did some checking with a few furnace repair men, and there is not alot of repairmen that run either acid or chemicals through the coil. They are recommending replacing the coil @$600.00. Yikes!! Another person suggested that since our water is extremely hard that instead of firing up the boiler during the summer, purchase an electric hot water heater and, that does self-cleaning of sedement buildup. This will stop our consumption of oil during the summer months, plus he also said that the coil is not needed for heating the house in the winter. He also said that we will continue to have the same problem year after year with the coil and it will become very costly because of the hardness of our water. Another suggestion was a water softener, that will have to wait until a later date because of our very tight budget. I think the electric hot water heater suggestion at this point is our best avenue to take. Thank you so much for your responses.
