You could get a new 83% gas boiler and save over your old unit,and have
cheaper gas to use for cooking and the dryer. Run your numbers before
you say no, I pay apx 1$ a therm Ng and 0.12kwh. electric for me is
several times more than gas or aps 3$ a therm, compared to Ng 1$ a
therm. Is you go all electric for cooking and your dryer and HW, you
will be paying many times more then if you convert. A new gas boiler may
save you 10-20% and yours is not new at all . I would go new boiler,
and tankless Takagi and a free gas line. The Takagi drawback is 2- 3
reduced flow showers at one time I dont find a drawback I like the
savings on my bill.
