["My husband is installing a wood boiler for our home to heat our house this Winter. I'm so impressed with him because he's doing it all on his own."]
That is impressive.  Is he normally pretty handy?
My husband undertook a huge project at our house this year. He is installing a wood boiler so we can heat our house with wood this next winter. I'm so impressed with him every day because he's doing it all on his own and he is succeeding amazingly well.
