....sent early by accident

I had a home energy audit done by RISE engineering. They recommend
installing a Burnham gas steam boiler with an AFUE rating of 82%-86%. The
price is $4900. They didn't mention a specific model number. Does anyone
have any experience with this brand? I have the option of adding a 41 gallon
indirect hot water heater (lifetime warranty, super insulated stainless
tank, unlimited supply...) for an additional $1800. An additional option is
a Tekmar outdoor heating system control for $800. I checked out the website
but I'm not sure exactly how this device is supposed to save me money. I
don't think I'm, going to go with the the two options just the new boiler,
but I'm interested in any advice or opinions.
Thanks
