Should an HRV to ERV be the primary exhaust for bathrooms?

Our house was build in 1990  1340 sq ft, and originally installed with an HRV that was also the primary exhaust for the 2 bathrooms and an additional exhaust vent in the kitchen area (plus a hood fan over the stove). We were told about 5-6 years ago that and ERV was better, so we switched. Venmar/AVS ERV EKO 1.5  The controls were completely different and we couldn't find anyone to help us. The motor or fan was loud, so we turned it off at night, and eventually, only turned it on to exhaust in the bathroom. However, even as a bathroom exhaust fan is didnt work well leaving smells linger and now our ceiling paint is peeling for the second time, after having it professionally painted. To assist the exhaust in the bathrooms, we've blocked the kitchen vent, but it hasn't helped. Our electrical bill spiked, so we thought we are also paying to heat too much exhausted air. Is this something that can be checked or confirmed?

Also how do we get it to be quieter?

Should we be using the "SMART" setting on the controls. So many questions.

Hope you can help -thanks!
