how can i send email through custom object?

I want to send email through custom object  

List<Messaging.SingleEmailMessage> allmsg = new List<Messaging.SingleEmailMessage>();
        EmailTemplate emailSickEmpTemplate = [Select Id from EmailTemplate where developername = 'Email_with_list_of_sick_employees'];
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        mail.setTemplateID(emailSickEmpTemplate.Id); 
        mail.setTargetObjectId(Userinfo.getUserId());
        mail.setSaveAsActivity(false);
        mail.setOrgWideEmailAddressId(owa.id);
        allmsg.add(mail);
        Messaging.sendEmail(allmsg,false);

This is the exception:

|SendEmail failed. First exception on row 0; first error: INVALID_TYPE_FOR_OPERATION, Only User, Contact, Lead, or Person objects are allowed for targetObjectId: a020v000002n3sr.: [targetObjectId, a020v000002n3srAAA]

Hi Kailash,

TargetObjectId parameter is used to set the recipient of the email. You cannot set that value to a Custom Object Id, If you are trying to send an email to a User selected on one of the lookups on the Custom Object Record, then query for the Id and assign that to TargetObjectId.

Try this
  
List<Messaging.SingleEmailMessage> allmsg = new List<Messaging.SingleEmailMessage>();
        EmailTemplate emailSickEmpTemplate = [Select Id from EmailTemplate where developername = 'Email_with_list_of_sick_employees'];
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        mail.setTemplateID(emailSickEmpTemplate.Id); 
        mail.setTargetObjectId(emailSickEmpTemplate.OwnerId);
        mail.setSaveAsActivity(false);
        mail.setOrgWideEmailAddressId(owa.id);
        allmsg.add(mail);
        Messaging.sendEmail(allmsg,false);

Hi,
I explored this topic in my own org, finally we cant send email through custom object Because salesforce doesn't allow mail.setTargetObjectId(custom_object_record_id) 
above solution will be send mail to owner of email template while i need to send email to the custom object.
