We also made a necessary, but perhaps less visible update to the building. We installed a new boiler and new hot water heater. Our old hot water heater was 25+ years old (they typically have a 15 year life span) and was leaking like a sieve. The boiler was 35 years old and it was time. Although these might not be the most attractive photos, they represent heat and hot water, something that I am thankful for daily.
Peace of mind that neither will break down in the dead of winter = priceless.
