80 bucks to clean a coil?

I'm trying to help out someone who has a problem where they have hot water for only a short time then gets cold. I dont know anything about their system except they said their heating company came out today and even though they have a contract, they said a specialist has to come out tomorrow to clean the coil for 80 bucks.

So is cleaning a coil that cheap and are there any inherent risks to taking one apart?

sorry but i have no more data than i've posted. I understand if it's not enough.

He's gonna boil out the minerals inside the coil with an acid solution. $80 seems like a fair price for a couple hours of work.

There's inherent risks in everything...

ok thanks, sounds like it's a legit fix then....just didnt know if she was getting ripped off. I also wonder what else her service contract doesnt cover?

I would not touch it for $80 with the hazzards and getting rid of the acid. Make sure that includes taking the acid away and not putting it down your drain.
Here is a new link to checking the DHW coil for problems.

this is nice...the guy from the 'pipe cleaners' showed up. He flushed the pipes, cleaned the coils and she said a ton of rust came out. Then she said that they still dont have hot water and that guy discovered the circulator isnt working. Another NON covered part under her contract.

she says thats another 350 or so for that.

Now you guys are the experts but how can you have a coil AND a circulator for DHW? I know my old boiler had the coil built in the side of the boiler. Is it that way for everyone that has a coil? and why would there be rust inside the drinking pipes?

when she mentioned circulator i just got to thinking about my new system with indirect and am wondering if she really does have an indirect. She did say she had a water heater tank so maybe the older ones had coils in them?

thanks for any advice in advance, i hate to see someone get scammed but i hope i'm just mistaken in what i think is going on

updated info..the person that did the coil used sound waves..not acid

also now they said she needs a new water tank and it will be 1250. I dont know how you go from just needing a coil cleaning to needing a circulator to now needing a new tank!

are they taking her for a ride?

Not an expert but the writing is on the wall.
it appears this heating system has not been checked properly over the years.
1. Was the contract in force for more then a few years. The contract should have included a maintenance check. Did you read her contract.
2. It does not sound like a good contract.
3. The company does not appear to be living up to its responsibilities to the customer unless the contact is useless.
4. I doubt that this lady can affectively communicate with you as to the problems.
5. If I were you, advise her to call her utility company to recommend a reliable inspector/serviceman to check it out or if its an oil burner, then call the oil company for a recommendation.
6. If this heating system is over 30 years old, then its near time to replace it.
7. Repeated service calls with discovery of other parts that failed and their costs to replace may make it worthwhile to get a new system.

Your friend probably has a coil / aqua-booster set up which basically is a giant Thermos for your coil. The aqua-booster is piped as a storage tank for the coil which has a built in aquastat that powers a bronze circulator. Here is a link to 1 manufacturer.

Domestic hot water components are not usually part of a standard service contract unless spelled out that they are and that is usually an extra cost. A coil can get scaled up on the inside and in the case of a tankless in the boiler it can also get coated on the outside if the heating system is really dirty.

I think i'm going to stay out of long distance helping out of penpals when i dont have a clue

but to close this thought/thread, i wanted to post her final result. She said she paid no extra cost , just the coil cleaning, and they were able to bypass the tank because it's a backup tank and she didnt need it. She said they freed up a valve on the boiler then had the coil cleaning guy back to hook something up to the burner. She also said she will do an annual coil clean from now on.

I dont understand , nor can i pretend to understand what's going on, i'm totally confused by it all... so i'm ducking out of it now. Thanks to everyone who tried to help and sorry I didnt have a clear pic of what was going on. Watch out for that snow! (got my bread)

Sound Waves?

Hey Lucky,
How's about seeing what you can find out about that rig? I can't imagine they pulled the coil & put it in an ultra sonic bath, especially for $80.
