Is there such a thing? I am looking to install a hot water boiler in my basement but don't really have the space since I am currently occupying some space for the forced hot air and central AC for the rest of the house and a hot water heater. So this is my thought, please tell me if I'm off:
I want to remove my hot water heater and install a tankless gas water heater and a small hot water boiler for basement heat, OR, can I buy a combo unit that will provide me with hot water to the house for showering, etc.. And hot water for heating the basement? Please help. Thank you in advance!

There are a couple wall hung units that will do what you want.

Quietside is one off the top of my head.

Lochinvar also makes a wall mounted boiler. you can then also get an indirect water heater (http://www.lochinvar.com/products/default.aspx?type=productline&lineid=50) this will use heat from the boiler to heat your domestic hot water. this will take up very little space and is super efficient.

Thank u HVAC 1000. Is this ok to do as far as efficiency and functionality? Do the heaters reduce in effectiveness when running hot water like showering?

If I understand your question right no running water while unit is on will not effect efficiency. These units are in fact very efficient and safe a lot of money over common tank water heaters
