heater warms up but not for long

This started yesterday.

My gas heater is a Kenmore RotoSwirl Model # 153.331882 S/N 1115A006193

It is connected to my Air Conditioning whatever it is the system called.

Weird thing is that the heating system heats up the home, but I open the hot water faucet and it comes up warm, almost cold, and lasts not many minutes that way and then water starts coming out cold.

I cannot take a warm shower, but the home is cozy...

I turned the heater in order for the water to come out hotter, the burner starts, I don't know for some minutes and then shuts off. If I open the hot water faucet the burner starts, but the water comes out barely warm. If it comes out as normally comes out (hot) it just lasts for a couple of minutes then starts to come out barely warm and then cold...

Any help will be appreciated.

T(h)ank you.

I'm completely lost.

That Kenmore is a gas fired water heater and should have no connection to your heating or air conditioning system.

It almost sounds like you have a tankless water heater. The kind that uses your boiler for hot water. We would need to see both units to see the connection between them.

Is it possible to take a picture or two of your setup there ?

PJ, I suspect that Chileno has one of those @#%&* systems that utilize domestic hot water through either a fan-coil unit (forced air) or radiant floor tubing for space heating. Even if I am correct we need a whole lot more information to make any kind of diagnosis.

Yes, it is one of those *&^%$# systems...

Aquatherm by First Co.


First Co. - 404


I hope the attached pics are not too small.

The house heating system is working ok, but I open any hot water faucet and it comes out hot for a moment then it cools down. In just 3 minutes or so.

Please help...

Thank you.

No, I cannot see any details in the pictures. I CAN tell you that somewhere there is a check valve not closing properly.

Ok.....I understand the principle here. That is an airhandler that uses your domestic hot water heater for its hot water.

Number one.....thanks for the pics but I can't see any detail in them. Like Furd said there must be a check valve and I'm thinking of a circulator pump too.

What doesn't make any sense is that if there is hot water available for heat.....why isn't it available for domestic use.

We have to see the plumbing to help you further.

PJmax and Furd:

Email me you personal emails and I will send you the same pictures but at a better resolution. The original pictures weigh about 1.40 mg each.

Thank you for your help.

I've got a better idea, upload the pictures to a free photo hosting site and then post the public URLs here.
