    This season i noticed the heat coming off my radiant fiin was not that warm as it was last year.. I had a stuck circulating valve fixed for the up stairs of the house.. Now my toe kick heaters in both my kitchen and bathroom and not blowing as hard as they use to aknd the heat coming off all my fin is very weak.. You got to put your hand rite on top of the radiant register to feel any heat.. Something is not rite.. I have 3 zones ( one upstairs one downstairs and one for my boilermate) my water for my shower is tolerable not overly hot.. Its used to be alot hotter.. What could be the problem.. I had the guy that installed it when it was new telling me it ok.. Everyone in the house is telling me there is something wrong with it.. We had to use electric heaters to keep from freezing ..

    Is the boiler actually hitting it's high temperature setting? Measure the temperature of the plumbing on the outgoing side of the heat distribution using an infra-red thermometer. If the plumbing is copper (which is highly emissive and will give a false low with an IR thermometer), apply a bit of spray paint (an non-metallic color) on the spots where you want to know the temperature.

    If the outgoing temperature is hot enough the flow may be too low, from either a restriction or a failing pump, or a partially closed valve.

    Is your domestic hot water supplied by an embedded tankless coil, or is it an indirect water heater?

    The water heater is a tank hooked to a zone of the boiler.. That water does seem to be hot but the water at my other 2 zones seem to be warm but is alot cooler ..it use to be very hot. Now its like luke warm heat at my toe kick heaters and nothing radiating off my baseboard like it did last year.. You have to put your hand rite on top of the baseboard to feel anything. The pump is very hot and real noisy.. I noticed since i quit use the boiler only use for hotwater now, my electric bill dropped 30.00 a month..

    I personally think along with people in my house that the hot water we use to shower with is not as hot as it was last year at all

    If the pump is noisy and over heated it's likely that the pump is failing.

    Terms like "hot", "luke warm", and "cooler" don't have firm definitions. How about some actual temperatures and settings?

    Most recent vintage Hydrotherm boilers have an external temperature gauge and an external control box that contains the aquastat controls (you need to pull the cover to see or adjust the aquastat.) To get more specific than that a model number would be useful.
