Peerless boiler and domestic hot water??

Hi, I have a Peerless oil fired boiler and baseboard hot water heat. I also get my domestic hot water from this.
I have very little water pressure with dom hot water. Nothing has been changed or adjusted it just gradually got down to little more than a trickle.

Is this the heating coil getting clogged in the firebox?
Also I would like to change my dom hot water to an electric water heater.
Can I just cut and cap the supply and return lines to the furnace or does it still need cols water feed for the home heating?
Any help is greatly appreciated.
Thanks
JZ

Domestic Hot Water

An electric water heater is the initially cheap but long term expensive way to heat water for domestic use. I would suggest an indirect.

If you want to go to an electric, you can just valve off the both sides & cut the pipes to the coil close to the boiler. They do not need to be capped. In fact, it is best to leave at least one side open.

Rather than an electric,which usually has a rather large operating cost,why not look into an indirect fired unit?

Indirect

An indirect is a water heater/storage tank which is heated by the hot water in the boiler. The big advantages over a tankless are: (1) You have storage capacity (usually about 40 gallons), (2) Your boiler fires only on demand from a zone (either the indirect or a heating zone) saving you a group of oil., (3) It has it's own thermostat so you can control the temperature of the domestic better.
Some examples of indirects are: Peerless's Partner: http://www.peerlessboilers.com/home/productcenter/index.cfm?fuseAction=details&psID=5

Thanks Grady, does this mean the water heater is heated from the hot water that heats the home? and not the dom water coil?
It seems I would pipe this into my house heating water cycle?
Thanks

It gets piped as a completely separate zone.

Indirect

If you download Crown's installation manual for their Mega-Stor it shows piping, controls, the whole deal.

Just click on the Mega-Stor link for the pdf file. Others, except for the Boiler Mate, are very similar.
